About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Yor-Lok Fittings for Stainless Steel Tubing

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. 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 A-Lok fittings.

316 stainless steel fittings have excellent corrosion resistance.

Straight Adapters, Tube × Flange

For Use With: Air, Cutting Oil, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Natural Gas, Steam, Water
Tubing: Use with welded or seamless 304/304L or 316/316L stainless steel that meets ASTM A213, ASTM A249, or ASTM A269

Fittings with flange end connect to another same-size flange with a gasket (sold separately) to create an access point in your line. They are also known as Pressure Class 150 flanges.

Sleeve and Nut Sets

Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser. To install them, slide off a set and place it on your tubing. Each front sleeve, back sleeve, and nut is made of 316 stainless steel for excellent corrosion resistance. Five sets of sleeves and nuts come on each dispenser. Sleeves are also known as ferrules.
