O-ring, 8 x 2 mm – Viton, Part# PL23970149 – vacstellar

Description

This O-ring is made from Viton (FKM). This is a special, high-performance rubber. It’s much better than ordinary rubber at handling heat, oil, and chemicals. Inside a vacuum pump, conditions can be tough. Viton stays strong and flexible much longer. This means your seal lasts longer and works better. An 8×2 mm O-ring is quite small. This means it’s perfect for sealing smaller connections and fittings. You might find it on sensor ports, small valve covers, or other parts of your pump. Even a tiny leak in these spots can affect your pump’s power. Replacing old, worn O-rings during service is a smart, low-cost way to keep everything running smoothly.
