4. FAQ
Q: What is the design purpose of combining three different raw materials together?
A: PU ensures elastic tight sealing, alumina filled PTFE reduces reciprocating friction, HNBR stops seal extrusion under abrupt hydraulic pressure surge.
Q: What structural design does this piston seal adopt for easy field mounting?
A: It features precision slit split design, allowing installation without complete piston disassembly during onsite maintenance.
Q: Can special color matching or modified raw material be customized for long-term bulk orders?
A: Regular inventory keeps natural material color; personalized formula development is available for fixed large-volume orders.
Q: What performance advantage does silver-grey PTFE layer have over pure solid PU seals?
A: Alumina filler inside PTFE improves wear resistance against tiny metal grit mixed in dirty hydraulic oil to extend service time.
Q: Will long running under continuous high oil temperature lead to yellow surface darkening?
A: Heat stabilizer added into raw materials restrains severe discoloration; slight color deepening never affects sealing tightness.
