Wills Rings® are designed for extreme conditions which exceed the capabilities of elastomer and polymer seals. They are metal seals which can be of two fundamental designs:
Wills Rings®O are the original Metal O-Ring seals and consist of a tube formed into a circular profile. Wills Rings®C are similar, but they have an open ‘C’ cross section. The open slot of the Wills Rings®C faces towards the system pressure and allows the seal to be pressure activated.
Wills Rings® are constructed from high quality metal tubing or strip in standard or thin wall thickness. They are often coated or plated with a softer material to increase their sealing performance.
Typical Oil & Gas Applications Include:
Because Wills Rings® are constructed from metal, their ability to handle extreme conditions exceeds that of polymeric and elastomeric seal types.
Wills Rings® seals do not suffer from the outgassing normally associated with elastomer seals that can be a problem when a seal is used on sensitive equipment.
