4. FAQ

Q: What is the core benefit of composite three-material construction?
A: PU maintains steady elastic preload for leakproof sealing, quartz-filled PTFE lessens reciprocating wear, EPDM prevents seal extrusion under fluctuating hydraulic pressure.

Q: What structural characteristic does this piston seal feature?
A: Entire closed seamless ring design, suited for deep fully enclosed piston grooves for stable mounting.

Q: Is custom color or adjusted material proportion available for large long-term orders?
A: Standard finished goods keep natural inherent color; personalized raw material formulation can be customized for fixed bulk contracts only.

Q: What performance difference exists between beige PU and silver-gray PTFE layer?
A: Quartz blended PTFE improves dimensional stability amid temperature swings, while beige PU provides elastic compression to block internal hydraulic leakage.

Q: Will long-period high-temperature running cause obvious discoloration or rubber bulging?
A: Anti-thermal aging ingredient is added into raw materials; mild surface darkening happens normally without deformation or sealing failure.

Q: How to differentiate piston seal ring from static plane gaskets?
A: This seal moves back and forth inside cylinder with piston, flat gaskets are sandwiched between two fixed metal joint surfaces for static sealing.
