O-ring, 50 x 3 mm – Viton, Part# PL23970211 – vacstellar

Description

This O-ring has an inner diameter of 50 mm and is 3 mm thick. This is specified by the pump manufacturer for a perfect fit. It is made from Viton (also called FKM). Viton is a very tough synthetic rubber. It resists oil, heat, and many chemicals very well. This makes it last much longer than standard rubber seals. O-rings are wear parts. Over time, they can become flat, cracked, or brittle. A worn O-ring causes air leaks. This makes your pump work harder and lose its vacuum power. Replacing old seals with this -quality O-ring is simple, cost-effective maintenance. It restores performance and protects your valuable pump.
