O-ring, 16 x 2.5 mm – Viton, Part# PL23970147 – vacstellar

Description

This O-ring might be small, but it has a very important job. It fits into a groove between two parts. When pressed, it creates a tight seal that keeps air out and vacuum in.

This seal is special because of what it’s made of: Viton (FKM). Think of Viton as a super-material for seals. It doesn’t give up when things get tough. It handles high temperatures and resists oils, fuels, and many chemicals. Ordinary rubber seals can fail in these conditions, but Viton stays strong.

That’s why Viton O-rings are a top choice for sealing vacuum pumps, fittings, and chambers. They are used in labs, factories, and research facilities everywhere. Using this O-ring means fewer leaks, better performance, and less worry about maintenance.

This is the official Part# PL23970147. Its inner diameter is 16 mm and it has a 2.5 mm thick cross-section. You can trust it to fit right and work right in your Busch equipment.
