Teflon® encapsulated silicone o-rings are a type of sealing gasket made from a silicone core that is encapsulated in a seamless and uniform Teflon® FEP which completely encloses a core of silicone material. This combination of materials provides a number of benefits, including improved chemical resistance, high temperature tolerance, and low friction. Teflon® also provides a smooth surface that can help prevent leaks and reduce wear on the o-ring. These o-rings are commonly used in a variety of industrial and automotive applications where a reliable, high- performance seal is required.
