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

Description

This O‑ring looks simple, but it does a very important job. It sits between two metal parts inside your vacuum pump. When you tighten those parts, the O‑ring gets squeezed. That squeezing action fills any tiny gaps in the metal surfaces. The result is a reliable seal that stops air and oil from leaking out. It also keeps dirt and dust from getting into your pump.
