These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

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

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

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

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

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

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

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

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

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

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.

Use these heavy duty forged flanges for high-pressure applications.

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

Bolt two same-size flanges together with a gasket to create an access point within a pipe line.

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.

The polished chrome plating not only has a shiny appearance, but also improves corrosion resistance on these Class 125 fittings.

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

Also known as Silbraze fittings.

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

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

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.

Connect these fittings to standard-wall plastic pipe for use in low- to medium-pressure applications up to 810 psi. They are the industry standard for residential and commercial plumbing and water supply applications.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Class 150 flanges. Use in high-temperature plumbing and water supply applications up to 200° F.

Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. They have the chemical resistance to stand up to acids, solvents, and other harsh substances. Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are also known as Class 150 flanges.

Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They have high strength and impact resistance.

These brass couplings have good corrosion resistance.

Fittings can withstand temperatures up to 200° F.

Use these nuts with brass compression fittings to create a seal on plastic tubing. They meet NSF/ANSI 61 for use with drinking water.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push, and an internal gripping ring and fluoroelastomer O-ring hold the tubing tight.

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

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Also known as I-line fittings, the flanged end of the male adapter on these high-polish fittings interlocks with the flanged end of the female adapter to provide extra support to your line.

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

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

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

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

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

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

Also known as JIS (Japanese Industrial Standard) fittings.

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

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

Couplings are plastic, which is lighter in weight than metal cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

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

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

Fittings are threaded on both ends so you can connect them directly to a threaded hose or to pumps, cylinders, and other equipment in your hydraulic system. Use in high-pressure applications up to 6,000 psi

Couplings are made of FDA listed materials, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Thread these caps and plugs onto fire hydrants and washdown equipment to close off the line. They have rocker lugs for easy gripping.
