Product Description Factory price Customized SIZE FKM NBR RUBBER MOQ1 PIECE Delivery time fastest 24hProduct Description Back-up rings are the most common anti-extrusion devices in dynamic sealing. They provide simple solutions to safely increase system function by positioning a more robust material adjacent to the extrusion gap, taking the seal's place and providing a barrier against high pressures. Back UPS can be used to offset the reduced pressure rating effects of wear rings or to improve seal against pressure spikes, or to ensure seal performance at higher tempertures.Backup rings serve as complementary components to O-rings in sealing systems. They effectively prevent O-ring extrusion, compression buckling, and nibbling damage, thereby significantly extending the service life of the O-ring. Additionally, backup rings enhance the O-ring's pressure-bearing capacity and improve its tolerance for radial clearance.PTFE is the most suitable material for the seal. PTFE is a semicrystalline thermoplastic material with exceptional chemical resistance and thermal stability. It exhibits the strongest corrosion resistance among all plastics, making it suitable for nearly all sealing applications.However, PTFE has slightly limited resistance to liquid alkali metals, elemental fluorine, and certain halogenated compounds.PTFE ideal for backup rings, V-rings. o-rings, rotary seals.and gaskets. FDA grades are available forfood and medical applications.Secondly,PTFE has a low friction coefficient, which makes it predestined for use in dynamic applications. FUNCTIONExcellent corrosion resistanceExtremely low friction coefficientGood high temperature resistanceSelf-lubricationGood sealing proformanceApplication:Suitable for dynamic, static, reciprocating, and rotational motion. Applicable to low to medium loads.Installation Guidelines:The use of backup rings can increase the working pressure and radial clearance tolerance of the O-ring seal.For single-direction pressure applications: Install one backup ring on the low-pressure side of the O-ring.For alternating or bidirectional pressure: Two backup rings are required - one on each side of the O-ring.
