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.

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.

The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings.

Create a leak-free, durable connection in plastic tanks, walls, or panels without gaskets or sealants.

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

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

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

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

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°.

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

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

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

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

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Made of brass, these fittings have good corrosion resistance.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Withstanding up to 300° F, these fittings have the highest temperature rating of all our brass push-to-connect tube fittings for air and water.

Fittings have good corrosion resistance.

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.

Couplings can handle pressures up to 250 psi.

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

Safe for use in your air brake line, these fittings meet Department of Transportation FMVSS 571 standards. They’ve been tested for thermal cycling, vibration, and burst pressure, so put them to work right away.

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

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.

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

Fittings have a sleeve that bites into tubing as you tighten the nut to form a seal in applications up to 120 psi. Also known as flareless fittings.

Fittings can withstand temperatures up to 200° F.

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