Kits contain Industrial quick-disconnect plugs in four coupling sizes so you can determine the size of your couplings without needing to measure.

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

With an unobstructed air path, these couplings have better airflow than other coupling shapes of the same size. Compatible with European-shape plugs and sockets.

Compatible with ARO-shape plugs and sockets.

Compatible with Japanese-shape plugs and sockets.

Plugs and sockets are color coded by shape so you can't mix hose lines. Only plugs and sockets of the same color will fit together.

Compatible with Ring-Lock-shape plugs and sockets.

Couplings have a spring-loaded locking sleeve that automatically locks into place to prevent accidental disconnection. The identical claw-style head connects to another spring-lock twist-claw hose coupling with a quarter twist.

Couplings are only compatible with other extra-large twist-claw hose couplings. Use with tools and equipment up to 2 pipe size.

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

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.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

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.

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

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.

Sets contain a crimping tool and a variety of CGA fittings, nuts, and ferrules so you can connect pressure regulators, torches, and other components of your welding system.

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

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

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

When space in your pipe line is limited, choose these miniature fittings that are one inch or less in length.

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

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

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

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

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.

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 Silbraze fittings.

Snap one of these rings into an unthreaded pipe fitting and braze to unthreaded pipe for an extra-strong, leak-resistant connection.

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

Use these corrosion-resistant fittings in a low-pressure pipe line.

The male threads on these fittings have a sealant applied for extra leak protection.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

When space is at a premium choose these compact fittings.

The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Class 6000.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Typically used with thin-wall stainless steel unthreaded pipe fittings.

Typically used with standard-wall and low-pressure stainless steel unthreaded pipe fittings.

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Class 3000 fittings.

Also known as Class 1500 steel flanges, these have the strength to handle high pressures.

Assortments contain threaded pipe in various lengths.

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.
