Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

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

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

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

When space is at a premium choose these compact fittings.

Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

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

Typically used with standard-wall and low-pressure stainless steel unthreaded pipe fittings.

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.

The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Pressure Class 6000.

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

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.

With an FEP sleeve and PTFE sealing tape, these connectors withstand chemicals better than rubber connectors. Use them for joining low-pressure chemical waste drainpipe and fittings or transitioning between different chemical piping.

Use in medium-pressure applications up to 230 psi.

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.

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications.

These joints are designed for vertical use in drain, waste, and vent systems.

These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant permanent connection.

Couple these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on stainless steel tubing.

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

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°.

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

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

Also known as I-line fittings, these fittings have a male adapter that interlocks with a female adapter for more support than standard quick-clamp fittings.

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

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.

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

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.

Bolt these fittings onto your ultra-high-vacuum chamber to transfer liquids and gases inside. Also known as feedthroughs, they come assembled with a flanged (CF) fitting, metal tubing, and two Yor-Lok tube 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.

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.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Ball bearings allow these fittings to rotate 360°, even after they are tightened. They have a special seal that reduces friction to allow for continuous rotation.

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

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.

Not only are these chrome-plated brass couplings corrosion resistant, they’re also durable enough to handle pressures up to 250 psi and can be used with vacuum.

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.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

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.

Connect tubing in sanitary food processing areas with frequent washdowns. They have a single sleeve (ferrule) that bites into hard metal and plastic tubing to make a seal—no heating, flaring, or soldering tools required.

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 150 psi.
