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.

Quick-Turn Couplings for Stainless Steel Tubing
- For Use With: Air
- Temperature Range: 32° to 350° F
- Tubing: Use with 304/304L or 316/316L stainless steel
Also known as luer lock couplings, these consist of a plug and socket that connect to small-diameter tubing with a half turn. They have a compact body for easy installation in tight spaces. Insert tubing into the plug or socket and tighten the nut to form a seal. Couplings are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They are 316 stainless steel for excellent corrosion resistance.
Note: For a complete coupling, order a plug and a socket.

- Temperature Range: -40° to 400° F
- Tubing: Use with seamless copper
- Specifications Met: ASME B31.3
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. Fittings are brass for good corrosion resistance. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.

Panel-Mount On/Off Valves with Yor-Lok Fittings
Easily access the handle of these valves while protecting your line behind an instrument panel. Threads and a hex nut below the handle allow you to install these valves in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Valves are standard port, so they slightly restrict flow.
316 stainless steel valves are more corrosion resistant than brass valves.
PTFE seals are the best choice for valves that are opened and closed often. The PTFE material forms a seal while remaining slippery, so you can open and close the valve frequently without the seal wearing down and failing.
PFA seals withstand high pressures and temperature changes. The plastic of the seal is nonporous, so it won’t trap gases or liquids that would weaken these seals.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
