How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

O-Ring Face Seal Fittings for Stainless Steel Tubing
- For Use With: Air, Hydraulic Fluid, Water
- Temperature Range: -30° to 250° F
- Tubing: Use with welded or seamless 316 stainless steel
- Specifications Met: SAE J1453; flared fittings also meet SAE J514
A tube adapter sits flush against the flat face of the fitting so you can slide the tubing and fitting sideways to disconnect in cramped spaces. Fittings are also known as zero-clearance fittings. To install, weld a tube adapter to the tubing with a brazing ring, then mate the tube adapter to the fitting and screw on the nut. As the nut is tightened, the tube adapter compresses the O-ring, creating a strong seal. Fittings are 316 stainless steel for excellent corrosion resistance. Nuts, tube adapters, and brazing rings are sold separately.
NPTF (Dryseal) threads are compatible with NPT threads.

O-Ring Face Seal Fittings for Steel Tubing
- For Use With: Air, Hydraulic Fluid
- Temperature Range: -30° to 250° F, except BSPP fittings are -20° to 230° F
- Tubing: Use with seamless steel
- Specifications Met: SAE J1453

To install, weld a tube adapter to the tubing with a brazing ring (sold separately), then mate the tube adapter to the fitting and screw on the nut. As the nut is tightened, the tube adapter compresses the O-ring, creating a strong seal. Fittings are zinc-plated steel for fair corrosion resistance. Nuts and tube adapters are sold separately.
