Color-code your lines by snapping these rings over the release ring on push-to-connect 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.

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.

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

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

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.

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

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.

Barbs grip onto tubing.

Fittings have good corrosion resistance.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

These fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

Use these to replace a damaged sleeve (ferrule) in quick-assembly compression nuts.

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They're moisture-resistant acetal, so they won't absorb water and soften, even in high-humidity environments.

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation.

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.

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

Also known as instant fittings, they 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.

Use these nuts with high-temperature compression fittings for food and beverage to create a seal on plastic tubing.

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.

Tube supports slip inside tubing to prevent the walls from collapsing.

Made of brass, these fittings withstand frequent washdowns in food-processing applications. They also adhere to NSF/ANSI safety standards, so they’re safe to use with food, beverages, and dairy.

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

Fittings can withstand temperatures up to 200° F.

Made of plastic, these sleeves create a strong seal without damaging tubing.

Made of nylon, these fittings are lighter in weight than metal barbed hose fittings.They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

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

Made of plastic, these fittings are lighter in weight than metal barbed fittings, yet have the chemical and corrosion resistance to stand up to harsh substances. Slide the barbed end into plastic or rubber hose and secure with a clamp.

Designed for coolant applications up to 200 psi, these fittings have a standard barbed end that slides into hose and secures with a clamp.

Couplings consist of a plug and a socket that connect more quickly than threaded garden hose couplings. To connect, insert the plug into the socket and press the levers down.

Attach cable, pipe, tubing, and other items to your strut channel.

Insert tubing into the fitting—no heat, solder, or flux required.

With internal components that resist wear from frequent operation, these valves can cycle as often as once per second.
