9 Best Matte Black Dishwasher Air Gaps (November 2026)
The best matte black dishwasher air gaps include the KRAUS Dishwasher Air Gap in Matte Black for a flush sink-deck finish, the PetrelWing Dishwasher Air Gap Kits with Black for a matching escutcheon, and the Moen Kitchen Air Gap for Moen replacement projects.
On this page (3 sections)
The best dishwasher air gap matte black option for most sink decks is the KRAUS Dishwasher Air Gap in Matte Black, with a solid brass cover and flush fit. PetrelWing adds a matching escutcheon, while AIR GAP INTERNATIONAL makes dual models for two dishwashers or a dishwasher and reverse osmosis system.
A black cap can tie the drainage fitting to a dark faucet, soap dispenser or sink accessory. The connection sizes and body height still matter: confirm the sink opening, hose routing and space below the counter before replacing a fitting.

KRAUS Dishwasher Air Gap in Matte Black: Best for a flush sink-deck finish
- Solid brass cover
- ABS plastic body
- Flush sink-deck or countertop fit
- 1 1/2 in pre-drilled hole
A solid brass cover and flush fit give this KRAUS kit a neat look beside matte black hardware. It is designed for compatibility with all dishwashers.
Pros
- Solid brass cover
- Flush cap covers the air gap body
- Corrosion-resistant finish
Cons
- Requires a 1 1/2 in pre-drilled hole
- Body is ABS plastic
The KRAUS kit suits a sink deck where you want the cap to cover the air gap body cleanly. Its solid brass cover has a matte black corrosion-resistant finish, and the ABS plastic body fits below it.
KRAUS gives an overall height of 9 in with the body, a cap height of 2 1/2 in and a cap diameter of 1 7/8 in. The required pre-drilled hole is 1 1/2 in, so measure the opening before choosing it.
The cover installs flush to the sink deck or countertop. KRAUS says the design is compatible with all dishwashers, and the kit includes detailed installation instructions.
Choose this for a standard single dishwasher and a flush deck look. If the opening or clearance differs, compare the dimensions with your existing fitting before ordering.
PetrelWing Dishwasher Air Gap Kits with Black: Best for a matching escutcheon
- Solid brass cap
- ABS plastic body
- Matching escutcheon
- Fits most dishwashers
The kit pairs a matte black solid brass cap with a matching escutcheon and plastic body. Its skirted cover is designed to cover the body and sit flush to the sink deck or countertop.
Pros
- Matching escutcheon included
- Solid brass cap
- Seven color options
Cons
- Confirm your sink opening and available clearance
- Body is ABS plastic
PetrelWing is a good fit when you want the cap and escutcheon to match. The solid brass cap and matching escutcheon cover the body for a tidy look at the sink deck.
Its cap measures 1 27/32 in across and 2 7/16 in high, with an overall height of 9 1/8 in including the plastic body. PetrelWing describes the kit as fitting most dishwashers, but checking the existing opening and hose route is still sensible.
The matte black finish is one of seven color choices. This kit is a straightforward option for a single air gap replacement when the matching escutcheon matters as much as the cap.
Choose it for a coordinated cap-and-escutcheon set. Consider the KRAUS if you need its specific 1 1/2 in hole requirement or prefer a known flush cap dimension.
Moen Kitchen Air Gap: Best for Moen replacement projects
- Matte black finish
- Authentic Moen replacement part
- Lifetime-guaranteed finish
- Designed for straightforward setup
This matte black Moen air gap is an authentic replacement part for a Moen fixture. The finish is backed by Moen's lifetime guarantee.
Pros
- Moen replacement component
- Matte black finish
- Finish guarantee from Moen
Cons
- Plastic construction
- Confirm it suits your existing setup
The Moen air gap fits best when you are replacing a Moen component and want a matte black finish. Moen identifies it as an authentic replacement part, and its finish has a lifetime guarantee from the brand.
The part is plastic and measures 1.94 x 1.94 x 2.19 in. Those measurements may describe the visible component rather than the full installed height, so check the model and fit against the part being replaced.
Moen describes installation as straightforward and positions this as a replacement for a malfunctioning air gap. It is a focused replacement choice rather than a full kit with published hose-connection dimensions.
Choose it when the Moen replacement fit is the priority. For a new installation where body height and hose sizes need to be matched, compare a complete kit with those dimensions stated.
Westbrass A200-1-62 1-3/4" x 2-3/4" Solid Brass: Best for a taller skirted cap
- Solid brass cap
- Plastic body
- Skirted cover
- Flush sink fit
Westbrass combines a taller matte black solid brass cap with a plastic body. The skirted cap covers the air gap body and fits flush to the sink.
Pros
- Taller cap than the other measured picks
- Solid brass cap
- One-year limited warranty
Cons
- Plastic body
- Check cap dimensions against nearby hardware
Westbrass suits buyers who want a taller skirted cap in matte black. Its solid brass cap is 2 3/4 in high, while the overall height with the plastic body is 9 1/8 in.
The cap diameter is 1 3/4 in, slightly narrower than the KRAUS cap. The skirted shape covers the air gap body and sits flush to the sink, according to the product description.
The kit includes the cap, flange and plastic body. Westbrass describes the fitting as an air gap for dishwasher drainage and gives it a one-year limited warranty.
Choose it if the 2 3/4 in cap height fits your available deck space. Measure nearby faucet handles or backsplash edges so the taller cover does not crowd them.
Adeaga Dishwasher Air Gap with Brass Cover: Best for stated hose connections
- Solid brass cover
- ABS plastic body
- 5/8 in dishwasher hose connection
- 7/8 in disposal hose connection
Adeaga gives connection sizes for both the dishwasher and disposal hoses, which helps when checking a planned replacement. The kit includes a matte black brass cap and ABS plastic body.
Pros
- Connection sizes stated
- Brass cap with matching escutcheon
- Installation instructions included
Cons
- Confirm hose fit before ordering
- Body is ABS plastic
Adeaga is useful when matching hose sizes is central to the replacement. It gives a 5/8 in dishwasher hose connection and a 7/8 in garbage disposal hose connection, along with a matte black brass cap and ABS body.
The skirted cover and matching escutcheon are meant to cover the body. The kit also includes installation instructions, and its listed dimensions are 1.8 in wide and 8.67 in high.
Adeaga describes the fitting as suitable for most dishwashers. Still, compare its connection sizes with your actual hoses and disposal inlet before choosing it, especially if your current setup uses adapters.
Choose this when both hose diameters match your setup. For more guidance on hose sizing and routing, see best dishwasher air gap drain hoses.
Dual Air Gap with Black Matte Brass: Best for two dishwashers
- Two 5/8 in dishwasher inlets
- 7/8 in outlet hose connection
- Extra-long threaded body
- Maximum flow rate of 11 GPM
This AIR GAP INTERNATIONAL model has two dishwasher inlets for separate dishwashers or a double-drawer unit. Its black matte brass cap is paired with a plastic threaded body.
Pros
- Two dishwasher inlets
- Both sides can operate at the same time
- Fits countertops up to 1 3/4 to 2 1/8 in thick
Cons
- Hose clamps are not included
- Outlet hose needs a route without sagging or loops
This dual air gap is designed for two dishwashers or a double-drawer unit. It accepts two standard 5/8 in inside-diameter hoses, and the maker says both inlets can operate at the same time.
The outlet connects to a 7/8 in inside-diameter hose leading to the disposal side connection. AIR GAP INTERNATIONAL says the maximum flow rate is 11 GPM, with 5.5 GPM per inlet, and the body fits countertops about 1 3/4 to 2 1/8 in thick.
The black matte brass cap sits on a threaded plastic body. Hose clamps are not included, and the outlet hose should route without sagging or loops.
Choose this for two dishwasher drain lines. If you need a single dishwasher connection instead, a standard single air gap has fewer ports to plan around.
Dual Air Gap with Black Matte Brass: Best for dishwasher and RO drainage
- Dishwasher and RO inlets
- 7/8 in outlet hose connection
- Push-in RO tubing connection
- Maximum flow rate of 11 GPM
This dual model connects one dishwasher and a reverse osmosis system with a tank to a shared drainage route. AIR GAP INTERNATIONAL says it is not compatible with reverse osmosis faucets with an air gap.
Pros
- Separate dishwasher and RO connections
- Push-in connection for RO tubing
- Fits countertops up to 1 3/4 to 2 1/8 in thick
Cons
- Not compatible with RO faucets that have an air gap
- Hose clamps are not included
The second dual model connects a dishwasher and a reverse osmosis system with a tank. It accepts a 5/8 in dishwasher hose and 1/4 in outside-diameter RO tubing, with a 7/8 in outlet hose.
AIR GAP INTERNATIONAL says the maximum flow rate is 11 GPM, while the RO port maximum is 1 GPM. The threaded plastic body is intended for countertops about 1 3/4 to 2 1/8 in thick.
This model has an important compatibility limit: AIR GAP INTERNATIONAL says it does not work with reverse osmosis faucets that already have an air gap. Its black matte brass cap is for buyers who need both drainage connections at the sink.
Choose it only when the RO system and faucet arrangement match those connections. For two dishwashers instead, the other dual model is the better fit.
WOWOW Kitchen Faucet with Air Gap: Best for a faucet and air gap set
- Matte black faucet
- Universal air gap kit included
- Pull-down sprayer
- Deck plate and adapters included
WOWOW packages a matte black pull-down faucet with a dishwasher air gap kit. It suits a coordinated replacement where both the faucet and air gap need attention.
Pros
- Faucet and air gap kit in one set
- Deck plate and adapters included
- Sprayer has three modes
Cons
- Faucet purchase may be unnecessary for an air gap replacement
- Check sink hole layout
WOWOW combines a matte black pull-down faucet with a universal dishwasher air gap kit. The set makes sense when both fixtures need replacing and you want their finishes to coordinate.
The faucet is deck-mounted, and the package includes the air gap cap, flange and plastic body, plus a 9.6 in deck plate and adapters. The sprayer offers stream, spray and dual-sweep modes, according to WOWOW.
This is a broader purchase than an air gap replacement. Check the sink's hole count and whether the faucet layout suits your counter before choosing the set.
Choose it for a faucet-and-air-gap refresh. If only the air gap needs replacement, one of the standalone kits avoids adding an unnecessary faucet.
Exakey Kitchen Sink Garbage Disposal Flange: Best for matching the disposal flange
- Matte black finish
- 304 stainless steel
- Fits a 3 1/2 in standard sink drain opening
- Stopper included
This is a disposal flange and stopper, not an air gap. It can help coordinate the disposal opening with matte black sink hardware when replacing an air gap separately.
Pros
- Matte black finish
- Stopper included
- 304 stainless steel
Cons
- Does not provide an air gap
- Check disposal and sink compatibility
The Exakey flange can coordinate the disposal opening with matte black sink hardware, but it is not an air gap. It is a garbage disposal flange and stopper made of 304 stainless steel.
It fits a standard 3 1/2 in sink drain opening and has a stated flange height of 1 3/4 in. Its stopper uses a push-and-twist action, according to the product description.
This can be a companion finish choice during a sink or disposal refresh. Keep the dishwasher air gap as a separate fitting, such as the KRAUS or PetrelWing kit above.
Choose it to match the disposal flange, not to replace an air gap. Check the sink opening and disposal compatibility before ordering.
What should you check before buying a matte black air gap?
Check the sink hole, deck clearance, hose sizes and drainage arrangement before choosing a finish. A cap that looks right can still be a poor fit if its body or connections do not match the installation.
Does the cap fit the existing sink hole?
Compare the required hole size with the opening already in your sink deck or countertop. KRAUS specifies a 1 1/2 in pre-drilled hole, while other products here provide cap or overall dimensions instead.
If the hole is larger or smaller, confirm whether the fitting can be secured safely before buying. Do not assume cap diameter and mounting hole size are the same measurement.
Will the finish look consistent with nearby fixtures?
Matte black can vary in tone and sheen between brands. Compare the air gap with the faucet, soap dispenser and sink accessories under the same kitchen lighting.
A coordinated kit can help. PetrelWing includes a matching escutcheon, while WOWOW pairs an air gap kit with a matte black faucet.
Which hose connections do you need?
A standard single air gap, a dual-dishwasher model and a dishwasher-plus-RO model use different inlet arrangements. Match the stated hose diameters to your existing hoses, then check the outlet route to the disposal or drain.
The air gap also needs to sit where its fitting can function as intended. For a plain-language overview, read What Is an Air Gap on a Countertop Dishwasher?.
Is a dual air gap right for your setup?
A dual model makes sense when two drainage sources need connections at one fitting. One AIR GAP INTERNATIONAL model takes two dishwasher hoses, while the other accepts one dishwasher hose and RO tubing.
See when to choose a double dishwasher air gap for the setup differences. If you are considering a hidden installation, read whether a dishwasher air gap can go under a sink and check local plumbing requirements before changing the layout.
Which matte black dishwasher air gap should you choose?
Choose KRAUS for a flush cap with a solid brass cover, PetrelWing for a matching escutcheon, or Moen when replacing a Moen part. For two dishwasher inlets or a dishwasher and RO connection, choose the dual model that matches those hoses.
Measure the opening and available deck space, then compare the hose route before deciding. An air gap belongs in a working drainage setup, so confirm local code and installation requirements as well as color.
The double dishwasher air gap guide explains when the extra inlet is useful.

Frequently asked questions
Does a matte black dishwasher air gap work like a standard air gap?
Yes. The matte black finish changes the visible cap, while the air gap's role is to help prevent wastewater from backing up into the dishwasher.
Choose a fitting with hose connections that suit your dishwasher and drain route, and follow local plumbing requirements.
How do I match a matte black air gap to my faucet?
Compare the cap color and shape with your faucet, sink and other deck fittings. Matte black finishes can vary between brands, so a coordinated set may look closer than parts chosen from separate product lines.
Also check cap diameter and the clearance around the sink hole.
Can I use a dual air gap with one dishwasher?
A dual air gap can serve more than one drainage inlet, but the extra connection should match the second appliance or system you plan to connect. The AIR GAP INTERNATIONAL models here are made for either two dishwashers or a dishwasher and a reverse osmosis system.
Check their connection sizes and compatibility before buying.
Can a dishwasher air gap go under the sink?
An air gap is generally installed above the sink deck or countertop, where its open fitting can function as intended. A hidden high loop is a different drainage arrangement and may not meet local code.
Check your local plumbing rules before changing the setup.
