Food Grade Clrar Silicone Rubber O-Rings 12mm OD to 85mm x 3.5mm CS

Silicone seals well, resists deformation and has excellent resistance to extreme temperatures. Silicone retains its performance in extreme heat and cold temperatures better than any other elastic material.

Dimensions shown are: Ring Outer Diameter (mm) x Rubber Width (mm). 

Namely in the dimensions: 12mm is the outer diameter and 3.5mm is the width of the rubber. (so the inner diameter is 12mm - 3.5mm -3.5mm = 5mm
