4. FAQ

Q: Why adopt three kinds of raw materials to form an integrated piston seal?
A: Aromatic PU provides lasting rebound tightness, feldspar-filled PTFE cuts sliding abrasion, NBR backup stops seal popping out under instantaneous hydraulic pressure peak.

Q: What unique structural design does this seal own for maintenance?
A: Double-gap split structure, convenient for snapping into piston groove without removing full piston assembly.

Q: Can special color customization or material reformulation be realized for large repeat orders?
A: Regular stock keeps original natural color; customized material formula is available only for long-term fixed bulk orders.

Q: What practical performance difference between almond PU and ash-gray PTFE layer?
A: Feldspar doped gray PTFE enhances anti-grit performance in contaminated hydraulic oil; almond PU relies on elasticity to block internal fluid leakage.

Q: Will long-term high-load operation make seal surface fade or deform dimensionally?
A: Heat-resistant additives restrain severe discoloration; slight surface darkening occurs naturally without influencing sealing efficiency.

Q: What construction equipment matches this piston seal exclusively?
A: Specially manufactured for wheeled rock haulers and small crawler graders with 3304/3306 engine configurations.

Q: How to distinguish piston seal from shaft rod oil seal in installation location?
A: This ring reciprocates inside cylinder along with piston; rod oil seal is fixed on cylinder end cover to seal rotating drive shaft.
