Patent

CA 2597510

The present invention provides a seal ring for placement in the space between a radial groove of a cylindrical member and a housing forming a bore in which the cylindrical member is movably positioned, which is free of scoring and has a fracture line through its thickness to form opposing faces. The faces are rough and mesh together such that when the faces are forced into contact, the faces are then interlocked. Furthermore, the seal ring has true roundness to enable the seal ring to seal the space despite presence of the fracture line. The seal ring is made up of a rigid polymer such as a polyimide, polyamide, polyester, polyetheretherketone, polyamideimide, polyetherimide, polyphenylene sulfide, and polybenzimidazole. The seal ring of the present invention is capable of single ring sealing of the space between the bore and the radial groove. The present invention also provides a device for fracturing the seal ring.
