4. FAQ

Q: Why combine three distinct raw materials to build one piston seal?
A: Aliphatic PU delivers sustained rebound force for tight sealing, feldspar-filled PTFE cuts abrasive friction, EPDM stops ring squeeze under sudden hydraulic pressure surge.

Q: What structural advantage helps field mechanics finish installation quickly?
A: Precision single-notch split design allows installment without fully disassembling the whole piston component.

Q: Is custom color or modified material formula available for bulk long-term orders?
A: Standard stock retains natural material color; customized raw material ratio is only accessible for confirmed large batch contracts.

Q: What functional difference between cream PU body and smoke-gray PTFE layer?
A: Mineral-filled gray PTFE resists erosion from grit-mixed dirty hydraulic oil; cream PU relies on elasticity to block inner medium leakage effectively.

Q: Will long-time continuous high-temperature operation lead to seal swelling or drastic discoloration?
A: Thermal stabilizer is blended in raw stock; only slight surface darkening appears with no dimensional change or sealing decline.
