Silicone O-Rings

Shop silicone O-rings by inner diameter and cross section in metric and AS568-style sizes. Silicone is often selected for wide-temperature flexibility, air, water, and static sealing where softness and low-temperature performance matter.

Silicone generally has lower tear and abrasion resistance than many other elastomers, so it may not suit high-wear dynamic service. Confirm fluid compatibility and operating conditions before ordering.
