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.

Cap For Tubing
Cap For Fitting
- 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
Caps for tubing have a nut and a sleeve so you can close off the end of your tubing in place of a fitting. Caps for fittings replace the nut and sleeve of an existing fitting.

Precision AN 37° Flared Fittings for Stainless Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -320° to 1200° F
- Tubing: Use with seamless 304 or 316 stainless steel
- Specifications Met: See Table
The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings. They are made to exact AS (formerly AN) specifications and provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Vibration-Resistant Precision AN 37° Flared Fittings for Stainless Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -320° to 500° F
- Tubing: Use with seamless 304 or 316 stainless steel
- Specifications Met: See Table
A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications. The threads on the tube end are Class 3A and adhere to tighter tolerances than other 37° flared fittings. They are made to exact AS (formerly AN) specifications and provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are 316 stainless steel for excellent corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.

Made to tighter tolerances than other compression fittings, these are designed for high-precision applications. Also known as instrumentation fittings and flareless fittings. They come with a nut and a single sleeve (ferrule). The sleeve bites into tubing as you tighten the nut to create a strong seal. Fittings are 316 stainless steel for excellent corrosion resistance. A molybdenum disulfide coating on the nut acts as a lubricant for easy installation.
