PTFE O Ring is mainly used for static sealing application in pipes, cylinders, bushings, stems, flanges and connections. Where chemical and physical inertia, as well as resistance to friction, temperature and ageing, are particularly strategic.
Backup rings are not seals themselves, but are used in conjunction with O-rings or other seals in high-pressure applications. Backup rings are installed in the downstream side of the gland, however, can be installed either side of the O-ring to give a high-performance double-acting seal.
