How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Yor-Lok Fittings for Stainless Steel Tubing

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.

Cleaned and Bagged Yor-Lok
Fittings for Stainless Steel Tubing

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

Precision AN 37° Flared Fittings
for Stainless Steel Tubing

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

Vibration-Resistant Precision AN 37°
Flared Fittings for Stainless Steel Tubing

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

37° Flared Fittings for Stainless Steel Tubing

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°.

Through-Wall Fittings for High-Vacuum Chambers

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

Compression Fittings for Stainless Steel Tubing

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

Precision Compression Fittings
for Stainless Steel Tubing

Yor-Lok Fittings for Copper Tubing

Precision Compression Fittings for Copper Tubing

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

37° Flared Fittings for Copper Tubing

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.

Compression Fittings for Steel Tubing

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

Yor-Lok Fittings for Steel Tubing

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

37° Flared Fittings for 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°.

Tube Fittings for Plastic and Rubber Tubing

Compression Fittings for Plastic Tubing—Chemicals

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.

Compression Tube Fittings for Food and Beverage

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.

Standard-Wall Plastic Pipe Fittings for Water

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.
