4. FAQ

Q: What structural feature makes installation more convenient for field mechanics?
A: It comes with precision single notch split design, enabling mounting without full piston disassembly during on-site repair.

Q: Can you develop custom colors or modified raw material formulations for large repeat orders?
A: Stock items maintain inherent natural colors from base materials; bespoke material ratios are available for long-term bulk cooperation only.

Q: Apart from color difference, what practical advantage does silver grey PTFE have over tan PU?
A: Barium sulfate blended PTFE boosts dimensional stability amid temperature fluctuation while tan PU focuses on flexible leakproof compression.

Q: Does continuous exposure to hot used hydraulic oil lead to seal discoloration or swelling?
A: Anti-oil additive is blended into raw stock; slight surface darkening is harmless and never triggers rubber bloating or leakage.

Q: Which engineering machinery matches this piston seal exclusively?
A: Designed for medium crawler excavators and small vibratory rollers running on 3304/3306 series engines only.

Q: How to distinguish piston seal ring from static flange gaskets in application scenario?
A: This ring reciprocates inside cylinder along with piston, while flat flange gaskets are sandwiched between two fixed metal connecting planes.

Q: Is individual piece purchase allowed rather than full bulk packaging?
A: Single-piece spot supply is available, full set purchase cuts average cost for regular equipment overhaul work.
