O-ring, 50.52 x 1.78 – Viton, Part# 320381 – vacstellar

Description

This o-ring has a specific size: 50.52 mm inside diameter and 1.78 mm thick. Using the correct size is important. If the o-ring is too big or too small, it will not seal properly. This part is made to fit exactly where it is needed. This o-ring is used in DVP LC.12 vacuum pumps. If you are rebuilding your pump or fixing a leak, having the right o-ring on hand makes the job go smoothly. It is always smart to replace o-rings when you have the pump open.
