This Viton O-ring is designed for exactly that.

An O-ring might seem like a simple part, but it has a very important job. It sits in a groove between two parts of your vacuum system. When tightened, it compresses to create a tight, leak-proof seal. This keeps air out and maintains the critical vacuum pressure inside.

it’s made from Viton (FKM). Viton is a special elastomer known for its excellent resistance. It handles higher temperatures and aggressive chemicals much better than standard rubber O-rings. This means it lasts longer in demanding conditions without hardening, cracking, or degrading.

Using the right seal is crucial. A worn or incorrect O-ring is a common source of vacuum leaks, which can hurt performance and efficiency. Replacing it with this quality part helps keep your system running smoothly and reliably.
