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.
- 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.

Couple these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on stainless steel tubing. Sleeves are 316 stainless steel for excellent corrosion resistance. They are also known as ferrules.
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.
