O-ring, 55 x 2 mm – Viton, Part# PL23970006 – vacstellar

Description

This Viton O-ring is built for the job. O-rings are simple but brilliant parts.

Imagine a soft, round rubber ring. When you press it between two surfaces, it squashes slightly. This squashing action creates a tight, leak-proof seal. It keeps air, oil, or other fluids from passing through.

This specific O-ring is made from Viton, which is a brand name for a special rubber called FKM. O-rings are used everywhere a perfect seal is needed. You might find them on inspection covers, valve fittings, or connection ports. Their job is always the same: to keep the vacuum tight and prevent leaks.
