Use these rings with quick-clamp high-vacuum fittings.

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

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.

Create an airtight seal between quick-clamp (ISO-KF) fittings—these rings complete high-vacuum connections.

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.

Made of plastic, these fittings are lightweight compared to our brass push-to-connect fittings.

Use these O-rings with brass compression tube fittings that have BSPP male threads. They create a seal on the BSPP male threads to guard against leaks.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

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.

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types.

Made of brass, these fittings have good corrosion resistance.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

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

Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards.

Connect air brake lines with fittings that won’t crack in sub-zero temperatures. They meet Department of Transportation FMVSS 571 safety standards, so they’re often used in commercial trucks and trailers.

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

Prevent mixing the wrong high-pressure lines—these couplings are designed to only connect with a plug or socket of the same color.

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

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Fittings are 316 stainless steel, which has excellent chemical resistance and is more durable than plastic.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line.

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.

Fittings can withstand temperatures up to 200° F.

These quick-disconnect couplings meet NSF/ANSI 169 for food equipment.

Create corrosion-resistant connections in food and beverage lines with just a push. Also known as instant fittings, these fittings have an internal gripping ring and an O-ring that hold tight to tubing.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

These quick-disconnect couplings mate with a sanitary stainless steel quick-clamp fitting for use in dairy lines.

Made of PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F.

Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly.

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

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

Also known as Code 61 SAE hydraulic flanges.

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

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

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT).

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

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.

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

When space is at a premium choose these compact fittings.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

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

Also known as Code 61 SAE hydraulic flanges, these let you create an access point in a high-pressure hydraulic line.
