O-ring, 157 x 3 mm – Viton, Part# 320379 – vacstellar

Description

This O-ring is built to last. It is made from Viton, a special type of rubber also called FKM. Viton is famous for being tough. It can handle high heat and contact with oils much better than standard rubber. This means it won’t crack or degrade quickly, giving you a reliable seal for longer.

The size is precise: 157 mm for the inner diameter and 3 mm for the thickness. Using the exact right size is critical for a perfect fit and a leak-free seal.

This part (#320379) is a direct replacement for specific pump models.
