4. FAQ

Q: What is the design intent of compounding three different raw materials?
A: Polyester PU maintains lasting elastic preload, glass-filled PTFE cuts abrasive wear, CR backup restrains seal extrusion under instantaneous hydraulic pressure surge.

Q: What structural characteristic facilitates field maintenance installation?
A: Equipped with precision single straight split, allowing installment without full piston disassembly on site.

Q: Is personalized color matching or modified material available for long-term bulk orders?
A: Standard stock retains natural material hue; customized ingredient proportion is open only for stable large-volume contracts.

Q: What functional gap exists between grey PTFE layer and sandy-yellow PU body?
A: Glass-powder PTFE strengthens anti-grit performance in contaminated hydraulic oil, PU relies on high elasticity to block internal oil leakage.

Q: Will long-cycle high-temperature running trigger obvious discoloration or volume swelling?
A: Anti-aging modifier is blended into raw stock; slight surface deepening is normal and never damages overall sealing tightness.

Q: Which construction equipment matches this piston seal exclusively?
A: Developed for articulated dump trucks and small track compactors fitted with 3304/3306 engine specs only.

Q: How does piston seal differ from end-face static gaskets in installation logic?
A: This ring reciprocates inside cylinder with piston movement; flat gaskets stay clamped between two stationary metal joint planes.

Q: Can buyers purchase individual rings instead of complete bulk packs?
A: Loose single-item supply is available, bulk procurement reduces unit cost for periodic vehicle overhaul.
