Silicone rubber gaskets are expertly cut from high-grade synthetic elastomer, delivering excellent non-stick characteristics and superior electrical insulation. This adaptable material maintains its flexibility and compression resilience even under extreme temperature conditions, making it a reliable choice for challenging sealing and gasket applications.
Thanks to their outstanding resistance to ozone, weathering, and oxidation, silicone rubber gaskets are particularly suited for outdoor and exposed environments. We offer specialist variants, including red oxide and 30° blue grades, which are WRAS approved and certified safe for potable water use up to +85°C. Our silicone gasket selection includes multiple colours compliant with FDA food contact regulations. Additionally,
metal detectable silicone gaskets are available to help reduce contamination risks in food processing settings.
Please consult the availability table and technical data sheets below for comprehensive details on material grades and specifications.
Our in-house manufacturing capabilities include precision CNC cutting, allowing us to supply everything from single prototype gaskets to large production runs. For assistance with measuring flange or picture frame gaskets, please refer to our detailed '
How to Measure a Gasket' guide.
