China Supplier NBR FKM Square Quad-Ring Rubber X Ring Custom X-Rings

Product DescriptionChina Supplier NBR FKM Square Quad-Ring Rubber X Ring Custom X-RingsX-rings can be used in a wide variety of static and dynamic sealing applications.  They are available in standard O-ring sizes.  Their four-lobed design provides a larger sealing area in comparison to a standard O-ring.  The double seal action requires lower squeeze levels to maintain an effective seal, thus reducing friction level and improving seal life.  X-ring parting lines are between the lobes, away from the sealing surface, therefore eliminating the problems of leakage often resulting from a parting lines irregular surface as found on an O-ring.  X-rings are designed to out perform a standard O-ring in rotary seal applications.  The four lobed configuration creates a more stable seal avoiding spiral twisting which can occur in reciprocating applications.  What's the difference between Quad Rings&O-Ring?Differences Between Quad Rings & O-Rings There are several main differentiators that separate standard O-Rings from X-Ring's four-lobed design. Standard O-Rings are built with a basic layout that provides simple leak protection, while Quad Rings have numerous advanced design qualities that allow them to provide enhanced protection. Quad Ring Seal's offer a unique spiral twist design coupled with an inner lobe sealing surface that allows for prolonged seal life and improved operational quality.Buna (or Nitrile) material is great for all but the most extreme applications. It works from -40-degrees F to 250-degrees F, and has good wear resistance. It works with oils.FKM (or Fluorocarbon) works for almost every application. It can withstand temperatures from -25-degrees F up to 400-degrees F.  MaterialHardness  (Shore A)TemperatureStandard SizeAvailableNBR(Buna, Nitrile)FKM(FPM)EPDM Silicone(VMQ)HNBR FFKM(FFKM, Kalrez)60~90 70~90 60~90 40~70 60~90 70~90 -40ºC-110ºC  -20ºC-220ºC  -45ºC-150ºC  -55ºC-204ºC  -48ºC-180ºC-18ºC-326ºCAS-568(USA)JIS-B2401(Japan)DIN-3771(Germany)BS-1516(UK)ISO3601(International)R(France)ID≤2000mm     CS≤40mmResistanceColorCertificateApplication Hydraulic Fluid  Engine OilChemical  Ozone & UV Steam & Hot Water  Low Temperature  High TemperatureBlack  Brown  Red  GreenWhiteBlue  ClearCustomizedISO9001SGSRoHSREACHAuto Industry  Construction Machinery  Machine Tool Equipment  Food Health  Water Treatment Chemical Processing  Hydraulic Pneumatic  Industrial Manufacturing   Detailed Photos   Company ProfileWe Tianjin SWKS is a manufacturer of rubber products and plastic parts with many year experience in China.
