Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

Typically used with low-pressure stainless steel threaded pipe fittings.

Typically used with low-pressure stainless steel threaded pipe fittings.

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

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

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

Typically used with extreme-pressure stainless steel unthreaded pipe fittings.

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

Typically used with low-pressure aluminum threaded pipe fittings.

Their small size makes these miniature fittings a good choice for cramped, confined spaces.

Typically used with high-pressure aluminum threaded pipe fittings.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Typically used with high-pressure brass and bronze threaded pipe fittings.

Typically used with low-pressure brass and bronze threaded pipe fittings.

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

Typically used with precision extreme-pressure brass and bronze threaded pipe fittings.

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Connect this pipe to standard-wall plastic pipe fittings in low- to medium-pressure applications up to 810 psi. It is typically used in residential and commercial plumbing and water supply applications.

Connect to barbed plastic pipe fittings with a clamp. Pipe isn't as bendable as soft tubing, but can still bend around objects, resulting in fewer connection points in your line. Fewer connection points not only shortens installation time, but also allows for smoother flow through the line.

Connect to CPVC pipe fittings for use in high-temperature plumbing and water supply applications up to 170° or 200° F.

This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand acids, solvents, and other harsh substances.

These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances.

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.

A turn of the T-handle will tighten and loosen these connectors, so you can quickly disassemble and reassemble your lines without tools.

Use in high-pressure applications up to 500 psi.

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

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

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.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

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

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

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

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

Use at pressures up to 4,300 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.

The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs.

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

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

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.
