M Barnwell Services stock a vast range (over 50 million pieces) of O Rings and Back-Up Rings and regularly supply Silicone O Rings to over 2000 customers.

All our Silicone (VMQ) seals offer a wide temperature range and have excellent resistance to ozone, weathering, and ageing. Compared with other elastomers, the mechanical properties are on the low side. They are also used by the Food and Drink, Brewing and Bottling, and Pharmaceutical industries.

Silicone material temperature resistance can be from –60°C to +250°C and resistant with water up to 100°C.
