Use these unions to connect different metals in a piping or plumbing system. They have a gasket with a plastic sleeve that inhibits destructive corrosion.

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

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.

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°.

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line.

Connect extra-support quick-clamp fittings for a fast and easy way to access your line.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Connect quick-clamp fittings in high-vacuum applications.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

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.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

Fittings are polished to a32 Ra and under finish on the interior.

Originally used on satellites, rocket propulsion systems, and even Mars rovers, these fittings will handle your most challenging industrial environments. They're designed to withstand high vibration and high vacuum without generating particles that could disrupt your operation.

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

Connect stainless steel tubing on one end and plastic tubing on the other end.

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings.

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

The threads on these fittings mate with NPT, NPTF, BSPT, and BSPP threads.

Made of EPDM, the gasket on these fittings stands up to the hot water found in heat exchangers and cooling systems. These fittings have stainless steel pipe threads, which are more durable than the plastic pipe threads found on other push-to-connect tube fittings.

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.

Made of stainless steel, these couplings stand up to wet environments.

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

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once.

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.

Connect tubing in sanitary food processing areas with frequent washdowns. They have a single sleeve (ferrule) that bites into hard metal and plastic tubing to make a seal—no heating, flaring, or soldering tools required.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 120 psi.
