O-ring, 53.34 x 5.33 mm – Viton, Part# 82018 – vacstellar

Description

Vacuum pumps work hard and get hot inside. This O-ring, part number 82018, is built to take it. It is made from Viton – a special black rubber that stands up to high temperatures and oils without cracking or swelling.

The size is 53.34 mm across the inside and 5.33 mm thick. When it sits in its groove and everything gets bolted together, it presses tight and stops leaks cold.
