Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

These brass fittings have the strength to handle high-pressure applications.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Install and remove these high-pressure brass fittings with a socket wrench or hex key (sold separately).

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

Extreme pressures are no problem for these heavy-duty brass fittings.

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

Typically used with low-pressure brass and bronze threaded pipe fittings.

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

Metal hose fittings have better durability than plastic barbed hose fittings.

Fittings are metal for better durability than plastic barbed hose fittings. They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

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.

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

Compatible with Lincoln-shape plugs and sockets.

Compatible with ARO-shape plugs and sockets.

Sockets accommodate five common plug shapes: Industrial, ARO, Lincoln, Tru-Flate, and European.

These couplings have a lower profile than other claw-style couplings to fit in cramped spaces. They consist of a plug and a socket that connect with a quarter twist. Also known as Bowes couplings.

Attach these fittings 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.

Use these CGA fittings to connect welding hose to pressure regulators and torches.

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.

These CGA adapters have a male threaded end that connects to a propane tank and a male threaded end that connects to welding hose.

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

Connect these fittings to fire hydrants and washdown equipment.

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

Use these couplings at pressures up to 6,500 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 Snap-Tite H-Shape plugs and sockets.

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.

Use these dust caps and plugs to keep contaminants out of your hose line.

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket that connect and disconnect quickly.

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

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

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.

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared fittings.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

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.

Withstanding temperatures up to 300° F, these fittings have the highest temperature rating of all our push-to-connect tube fittings for air and water.

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

Use at pressures up to 150 psi.

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.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Tube supports slip inside tubing to prevent the walls from collapsing.

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

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

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

Fittings have good corrosion resistance.

Couplings can handle pressures up to 250 psi.
