Nickel-Plated Brass Push-to-Connect Tube Fittings for Air
(SAE Straight) Male
Threads with Gasket
- For Use With: Air, Lubricated Air
- Temperature Range: 0° to 140° F
- Tubing: Fittings with Release Ring and Fittings with no Release Type: Use with firm or hard (Durometer 95A-60D) nylon plastic, polyethylene plastic or polyurethane rubber
Fittings with Release Sleeve: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber
Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring or sleeve and pull the tubing out of the fitting.
Fittings with release sleeve are easier to disconnect than fittings with a release ring because they are seamless and won't collect dirt and debris.
Metric and UN/UNF (SAE Straight) male threads with gasket or thread sealant provide extra protection against leaks.

Brass Quick-Turn Tube Couplings for Air
An all-brass body gives these couplings better strength and durability than plastic quick-turn couplings. They have a nickel plating for extra protection against corrosive environments. Also known as luer lock couplings, they consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body, so they’re easy to fit in tight spaces. Plugs and sockets are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.
Note: For a complete coupling, order a plug and a socket.

Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance.Aluminum fittings are lighter in weight than other metal fittings. They have good corrosion resistance.
Stainless steel fittings have very good corrosion resistance. 303 stainless steel fittings won’t rust when exposed to water, making them good for areas that require frequent cleanings. Fittings with a threaded end are also known as hose nipples.

Right-Angle Flow Rectangular Manifolds
Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers. They have mounting holes, so you can mount from the top or side.
Aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. Anodized aluminum manifolds have a black finish and nickel-plated aluminum manifolds have a shiny finish.

Low-Profile Hex Manifolds
When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air, water, or hydraulic fluid to five locations from a single supply source. Manifolds have mounting holes, so you can mount from the top.
Anodized aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. These manifolds are anodized for a black finish.
316 stainless steel manifolds have excellent corrosion resistance and can handle fuel, gasoline, coolant and other harsh substances.

Grease Fitting Adapters
When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.
Zinc-plated steel adapters have mild corrosion resistance. Brass adapters resist corrosion better than zinc-plated steel adapters. UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.
For technical drawings and 3-D models, click on a part number.
Button-Head Grease Fittings
Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won’t pop off when adding grease. They're best for machinery requiring high volumes of grease because they let more grease pass through than standard grease fittings, thanks to a larger opening. An integral check valve prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.
Zinc-plated steel fittings have mild corrosion resistance.
