O-ring, 2.1 x 1 mm – Viton, Part# 320210 – vacstellar

Description

This O-ring has an inside diameter of 2.1 mm and a thickness of 1 mm . That is a very small size. It is used in locations where larger seals cannot fit. It sits snugly in its groove. When you tighten the parts together, it compresses and creates a tight seal. 

This O-ring is a direct replacement. It fits right into the groove. Because it is so small, you may want to use tweezers to place it carefully. No cutting or gluing is needed. Just place it in position and assemble the parts.

Choose this Viton O-ring for a reliable seal. It helps your Pfeiffer pump keep working the way it should
