PTFE+Bronze Brown Color Back Up Ring Hydraulic Cylinder Rod Seal Back Up Ring
Hydraulic PTFE Seal Back UP Ring are used for static and dynamic applications. It's better used for static sealing applications with corresponing O-ring.
The use of PTFE backup ring will help control O-ring and rod seal extrusion in high pressure applictions. PTFE backup rings are compatible with all hydraulic fluids,since they are virtually chemically inert,and also can be used in applications involving elevated operating temperature conditions.In addition,PTFE backup rings can greatly improve O-ring and rod seal performance and extend service life, even if extrusion does not present a problem.
