O-ring, 59 x 3.0 mm – Viton, Part# 4070874 – vacstellar

Description

This O-ring has an inside diameter of 59 mm and a thickness of 3 mm . That is the perfect size for several Pfeiffer pump models. It fits snugly in its groove. When you tighten the parts together, it compresses just enough to create a leak-proof seal. 

This O-ring is a direct replacement. It fits right into the groove. No cutting or gluing is needed. Just place it in position and assemble the parts.

Choose this Viton O-ring for a reliable seal.
