Silicone offers a wide temperature operating range while maintaining flexibility.  Ideal for high temperature locations such as where a connection will exist in the heat wash of a burner.  Softer than the PTFE Teflon tri clover gasket, this silicone tri clover gasket is is easier to keep a drip free seal across a wider temperature range. These very hard to find gaskets are in stock and ready to ship.

Temperature range is -46*F to 446*F
