Rings for Claw-Clamp and Bolt-Together
High-Vacuum Fittings for Stainless Steel Tubing

Ring

For Use With: Air
Max. Temperature: 400° F
Tubing: Use with 304/304L Stainless Steel or 316/316L Stainless Steel

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings. They contain a Viton® fluoroelastomer O-ring—when you clamp or bolt your fittings together, the O-ring compresses to establish the seal.
