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

Use these sleeves with compression nuts and fittings to create a strong seal on stainless steel tubing.

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.

Tighten these nuts onto high-pressure compression sleeves and fittings to create a strong seal on stainless steel tubing.

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

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

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

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°.

Quickly connect low-pressure stainless steel lines with these couplings. Made of 316 stainless steel, they have excellent corrosion resistance.

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.

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.

Create a strong connection without heating, flaring, or soldering.

Use these nuts with compression sleeves and fittings to create a strong seal on copper tubing.

Use these sleeves with compression nuts and fittings to create a strong seal on copper tubing.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

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

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

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

Use these nuts with compression sleeves and fittings, also known as bite fittings, to create a strong seal on steel tubing.

Use these sleeves—also known as ferrules—with high-pressure compression nuts and fittings. They withstand about twice as much pressure as sleeves for standard compression fittings, so they’re good for hydraulic power applications.

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

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.

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.

Use these sleeves with brass compression nuts and fittings to create a seal on plastic and rubber tubing.

Use these O-rings with brass compression tube fittings that have BSPP male threads. They create a seal on the BSPP male threads to guard against leaks.

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.

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

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.

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.

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.

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 PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F.

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

Use these nuts and sleeves with compression fittings for food and beverage to create a seal on plastic 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.

The female connector screws directly onto the hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.

Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required.

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

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 medium-pressure applications up to 230 psi.

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

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.

Made of polypropylene, this gravity-flow pipe stands up to tough organic solvents, such as acetone, that would dissolve CPVC pipe. You can also use it for lines with highly corrosive acids, such as hydrochloric acid, and alkalies.

Use these clamps to connect easy-access CPVC pipe fittings and pipe.

Also known as Victaulic fittings, these have grooved ends that connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. Fittings have excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances.

The grooved ends on these iron fittings connect to pipe with a clamp to easily install piping systems.

Also known as no-hub pipe fittings and soil pipe fittings, these fittings are for use in gravity-flow applications both above and below ground.
