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.

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
Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs. Because they form a tight seal on chamber walls, they are often used in coating, cooling, and leak-testing applications where negative pressure (vacuum) must be maintained. These fittings are ready to install and include high-vacuum fittings, metal tubing, and Yor-lok tube fittings. On each end, the Yor-lok fittings include a nut and two sleeves that grip your system’s stainless steel tubing. The entire assembly is stainless steel, so it resists rusting. These fittings are not for use in pressure applications.
Quick-clamp fittings meet ISO 2861, which specifies the dimensions of quick-clamp high-vacuum fittings, clamps, and rings to ensure vacuum tightness. These fittings require a clamp and ring (each sold separately) to complete the connection.
Flanged fittings require a gasket and bolt kit (each sold separately) to complete the connection.
