Silicone O-Rings Selection Guide

Silicone o-rings are excellent seal materials for high temperatures in static environments. Typically, silicone

o-rings show outstanding flex and fatigue life, strong ozone and UV radiation resistance, and physiologically

neutral and insulating properties. Silicone o-rings can be synthesized with a wide variety of properties and

compositions, allowing for great flexibility in performance.

ORK Rubber has millions of standard and non-standard silicone o-ring sizes in-stock, and the ability to

custom-make o-rings upon request, often without tooling fees. Order silicone o-rings from the world’s largest

o-ring inventory network, including:

· High temperature silicone gaskets and o-rings

· FDA food grade silicone seals and o-rings

· USP Class VI medical-grade silicone gaskets and o-rings
