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.

Brass and Bronze Unthreaded Pipe Flanges
Bolt these flanges to equipment or to another same-size, flat-surface flange with a gasket (sold separately). They have good corrosion resistance.
Cap flanges are also known as blind flanges.

- For Use With: Air, Argon, Natural Gas, Nitrogen Gas, Oil, Oxygen, Water
- Class: 150
- Specifications Met: ASME B16.24
- Pipe Nipples and Pipe: Use Schedule 40 brass

Through-Wall Fittings for High-Vacuum Chambers
- For Use With: See table
- Environment Temperature Range: 32° to 300° F
- Process Temperature Range: -325° to 995° F
- Tubing: Use with 304/304L or 316/316L stainless steel
- Specifications Met: See table
Also known as feedthroughs, these fittings transfer liquids, cryogenic liquids, or gasses into high-vacuum chambers for coating, cooling, and leak-testing applications without losing vacuum pressure. Consisting of high-vacuum fittings, metal tubing, and Yor-lok tube fittings, these complete assemblies come ready to install. The quick-clamp (KF) or flanged (CF) high-vacuum fittings form a tight seal on chamber walls. On each end, the Yor-lok fittings include a nut and two sleeves that grip your system’s stainless steel tubing for a leak- and gas-tight connection. The entire assembly is stainless steel so it resists rusting. Not for use in pressure applications.
Flanged fittings require a gasket and bolt kit (each sold separately) to complete the connection.
