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

A built-in shut-off valve stops the flow when the coupling is separated, so there’s no need to worry about air or water spilling from your line. Couplings are plastic, which is lighter in weight than metal couplings.

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

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.

Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage.

Fittings withstand temperatures up to 220° F.

Made of FDA listed materials, these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

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

Fittings have a barb that grips onto tubing. Use in applications up to 150 psi.

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

Use these tools with a crimping ring (sold separately) to connect barbed tube fittings for drinking water to tubing.

Fittings have a barb that grips onto tubing. Use in applications up to 150 psi.

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.

Use at pressures up to 4,300 psi.

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

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

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

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

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

These fittings have the highest pressure rating of all the Yor-Lok tube fittings we offer.

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.

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

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

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

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

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

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.

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 steel tubing that is flared to 37°.

Also known as JIS (Japanese Industrial Standard) fittings.

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight seal on tubing that is flared to 37°.

With the best corrosion resistance of any metal fitting we offer, these Hastelloy fittings will stand up to aggressive chemicals and are resistant to pitting and stress cracking. Also known as instrumentation fittings, they include a nut with two sleeves.

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

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Bolt two same-size flanges together with a gasket to create an access point within a line. Made of PTFE, they can handle a wider temperature range than any of our other plastic pipe flanges for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.
