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.

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 Ring-Lock-shape plugs and sockets.

A slim body allows these couplings to fit into tight spaces. Compatible with Compact-shape plugs and sockets.

Compatible with Japanese-shape plugs and sockets.

Compatible with Schrader-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.

Attach these chucks to your air hose so you can connect the hose to Schrader valves.

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.

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.

Typically used with high-pressure iron and steel threaded pipe fittings. Also known as Schedule 160.

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

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

Use these fittings for low-pressure applications in noncorrosive environments.

The threads on these fittings have clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end.

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

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

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

The grooved ends on these iron fittings connect to pipe with a clamp to easily install piping systems.

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

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

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

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

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

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.

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

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

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

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

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.

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