O-ring seal

PTFE

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. Why Order from Us? For over one decade, Dechengwang has been a leader in servicing and supplying our customers with only the best quality O-Rings and machined plastics all at competitive pricing. With so many applications across so many industries, it’s easy to see why manufacturers turn to PTFE or compounding O-rings when they seek a quality sealing solution. You can find our O-rings perform well in such industries as:Food and beverage/Mechanical Engineering Automotive/Electronics & Semiconductors/Aerospace/Oil & Gas Designed for Your Application: -Low friction coefficient -Functions at temperature extremes -Excellent moisture resistance -Good cryogenic capabilities -Good tensile strengthPTFE Back-upRingBackup rings provide additional extrusion resistance and prevent damage to O-Rings and seals.Backup rings are not seals themselves, but are used in conjunction with O-rings or other seals in high-pressure applications.
