A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types.

Made of brass, these fittings have good corrosion resistance.

The threads on these fittings mate with NPT, NPTF, BSPT, and BSPP threads.

Connect air brake lines with fittings that won’t crack in sub-zero temperatures. They meet Department of Transportation FMVSS 571 safety standards, so they’re often used in commercial trucks and trailers.

Designed for use in welding applications, these fittings are flame retardant.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to holds the tubing in place.

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.

These compression tube fittings meet Department of Transportation FMVSS 571 safety standards for air brake lines.

Couplings can handle pressures up to 250 psi.

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

Use these sleeves with compression nuts and fittings to create a strong seal on copper tubing.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

Add a push-to-connect junction to unthreaded ports for easy connections with tubing. To install, drill a stepped hole in your surface, push the fitting components into place, and insert your tubing.

Create a leak-tight seal without using heat or solder. Slide copper tubing into a press-connect fitting and use these tools to crimp the connection.

Repair leaks in copper tubing.

Eliminate sharp bends at the end of your air and water hose—these fittings have a built-in kink absorber.

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

The female connector screws directly onto the hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.

Couplings allow for maximum flow because there's no shut-off valve in the plug or the socket. Compatible with Open-Flow-shape plugs and sockets.

Compatible with ARO-shape plugs and sockets.

Also known as automotive couplings. Compatible with Tru-Flate-shape plugs and sockets.

Compatible with Lincoln-shape plugs and sockets.

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO B-shape plugs and sockets.

Made of brass with a steel wing nut, these couplings are tough enough to handle occasional drops to concrete and frequent connections on dump truck, oil rigs, and other heavy duty equipment. Compared to push-to-connect couplings, these are threaded, so they're easier to connect when there's pressure in your line.

These CGA adapters allow you to connect a hose to a propane torch.

Commonly used in low-pressure welding applications, these fittings connect downstream of your pressure regulator. Slide the barbed end into hose and secure with a crimp-on hose ferrule.

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

Fittings meet NSF/ANSI Standard 61 for drinking water. Attach them to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

These two-piece couplings thread together to create an access point within a garden hose line. The threaded design allows for a more secure hold at the point of connection than quick-disconnect and cam-and-groove garden hose couplings.

The rocker lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment.

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

Stop leaks from variations in temperature and vibration that can loosen 45° flared tube fittings.
