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.

These fittings have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. They are commonly used in metal surface treating applications, plating solution lines, and other chemical process applications. Reinforced with layers of fiberglass, they have better strength and durability than any of our other pipe fittings for chemicals.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Also known as dry disconnects and double shut-off couplings, these couplings make connecting and disconnecting your line quick and virtually spill-free. Built to stand up to petroleum products, such as diesel fuel and gasoline, their body and gasket are made from materials that won’t corrode from oil.

Access your line without twisting the hose—these unions separate into three pieces.

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

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

Use these nuts with compression sleeves 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.

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.

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared fittings.

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.

Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser.

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.

Use with soft plastic tubing to prevent the tube from collapsing.

Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser.

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

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

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

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.

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.

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

Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Also known as JIS (Japanese Industrial Standard) 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.

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.

For installation through thick insulation, these valves have an extra-long stem.

To withstand aggressive and corrosive solutions in miniature chemical-processing pipelines, these tiny valves have a chemical-resistant fluoroelastomer seal and a corrosion-resistant 303 stainless steel body.

There’s no need to unbolt these valves for cleaning—remove the valve handle and slide the valve apart for inline access to internal components. Also known as elliptical valves, they have a fluoroelastomer seal and a polypropylene body to withstand aggressive and corrosive solutions in chemical-processing applications.

Insert tubing into the fittings on these valves—no heat, solder, or flux required. To withstand aggressive and corrosive solutions, they have a chemical-resistant fluoroelastomer seal and a plastic body.

Bolt these valves to ANSI flanges—they meet ASME dimensional standards. They have a plastic body and a seal that withstand aggressive and corrosive solutions in chemical-processing applications.

No need to completely remove these valves from your line for servicing. The bolted three-piece body comes apart, so you can easily access their internal components. Fire-tested to meet American Petroleum Institute (API) 607, these valves securely isolate diesel fuel, fuel oil, kerosene, and gasoline to prevent the spread of fire.

Keep your worksite safe when working with diesel fuel, fuel oil, gasoline, and kerosene. Fire-tested to meet American Petroleum Institute (API) 607, these valves are designed to securely isolate fluid and prevent the spread of fire.

For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Use with diesel fuel, fuel oil, gasoline, and kerosene.
