O-Rings

Silex offers a range of manufacturing methods for producing silicone rubber O-rings including bonding cord, strip or tubing into rings, or moulding them for ultra-precise O-Rings without a join.

Unlike other kinds of O-Rings, silicone offers excellent temperature, chemical and environmental resistance, and can be produced in a wide range of material grades including FDA compliant and high and low temperature options.

Silicone O-Rings are excellent for sealing applications requiring longevity, Ozone and UV radiation resistance.

Availability

O-Rings can be quickly and cost-effectively produced from any of our stock materials, or we can extrude sections in special materials, colours, hardnesses or sizes for joining on request. 

Where a join isn’t acceptable, O-Rings can be moulded with a small tooling charge.
