The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

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

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.

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.

Made of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. Compatible with Plastic-shape plugs and sockets.

Compatible with Lincoln-shape plugs and sockets.

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

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

Couplings can handle pressures up to 250 psi.

Made of brass, these couplings are more durable than plastic couplings.

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

A built-in shut-off valve stops the flow when the coupling is separated, so there’s no need to worry about air or water spilling from your line. Couplings are plastic, which is lighter in weight than metal couplings.

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

Also known as JIS (Japanese Industrial Standard) fittings.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight seal on tubing that is flared to 37°.

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

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.

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.

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

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

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.

When space is at a premium choose these compact fittings.

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

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

Suitable for use in fire-protection applications, these pipe fittings are made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer.

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

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

The heavy duty caps and plugs in these assortments come in various sizes and stand up to high-pressure flow applications. Made of steel, they’re for use in noncorrosive environments.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

Also known as pneumatic plugs, these plugs conform to wide and out-of-round pipes.

These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line.

Plug underground sewage lines, water supply lines, and other pipe that’s hard to reach. These plugs connect to a 6-ft. extension pole with an adapter so you can place them in confined spaces from a distance.
