These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe 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.

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

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

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.

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

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 Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

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. Use in high-temperature plumbing and water supply applications up to 200° F.

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Fittings resist acids, solvents, and other harsh chemicals. They won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.

Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket to create an access point within a line.

These brass couplings have good corrosion resistance.

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

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.

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°.

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, these quick-clamp fittings permit easy access to your line.

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.

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

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.

Also known as JIS (Japanese Industrial Standard) fittings.

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

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

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.

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

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

These caps are the fastest way to close off or access your water line. They have a bracket that snaps into any type of 2 1/2 size female fire hose threads. Tap on one of the pin lugs to remove quickly in an emergency.

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.
