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

Cleaned and Bagged Yor-Lok Fittings for Stainless Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -420° to 1200° F
- Tubing: Use with seamless or welded 304/304L or 316/316L stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination. They include a nut with two sleeves (ferrules) for 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, or A-Lok fittings. Fittings are 316 stainless steel for excellent corrosion resistance. Replacement nuts and sleeves are not cleaned and bagged.

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.

Brass Compression Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water
- Temperature Range: See table
- Tubing: Use with firm or hard (Durometer 1A-95A or Rockwell 15T 1-15T 60) nylon plastic, polyethylene plastic, polypropylene plastic or polyurethane rubber
- Specifications Met: SAE J512, except metric sizes
A single sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. They are brass for good corrosion resistance.
Tube supports (sold separately) are recommended if you want to use the fittings with soft polypropylene and polyethylene tubing to prevent the tube from collapsing.
Install plugs with a nut (sold separately) on the end of fittings to block the flow of air or water.
