O-Ring,Viton,62 x 3.53 mm

This o-ring has a 62 mm inner diameter and a 3.53 mm cross-section. That means the rubber ring itself is 3.53 mm thick .

The 3.53 mm thickness is a standard AS568 size (also known as a -2xx series dash number). It is a common industrial size. The 62 mm inner diameter makes this a mid-size o-ring, used in many pump applications.

Viton is a brand name for a type of synthetic rubber. The technical name is FKM (Fluoroelastomer). Viton is special because it can handle :

• High temperatures – Much hotter than standard rubber

• Harsh chemicals – Oils, fuels, acids, and solvents

• Vacuum pressure – It holds its shape even under strong vacuum

Standard rubber o-rings can swell, crack, or melt in these conditions. Viton keeps working.
