O-ring, 188 x 3 mm – Viton, Part# 706583 – vacstellar

Description

This O-ring is a round rubber ring. It may look simple, but it does a very important job. It sits between two metal parts inside your vacuum pump. When you tighten the parts, the O-ring gets squeezed. This squeezing action fills up any tiny gaps. It stops air and oil from leaking out. It also stops dirt from getting in. It is also part of the complete Gasket Kit (Part# 1027280101)
