4. FAQ

Q: Why adopt double-layer composite structure instead of single raw material?
A: PU layer supplies reliable elastic compression, filled PTFE lowers friction against cylinder barrel, NBR back-up prevents seal popping out under high hydraulic pressure.

Q: What forming style is applied for this piston seal during production?
A: It is an integral closed ring structure without cutting split, suited for deep piston groove installation.

Q: Is customized color or reformulated raw material available for big batch orders?
A: Standard items retain natural inherent color; bespoke material can be developed upon formal bulk purchase agreement.

Q: What practical superiority does PTFE surface bring compared with all-PU single seal?
A: Filled PTFE effectively blocks gritty impurity abrasion from contaminated hydraulic oil and prolongs service cycle greatly.

Q: Does continuous working under elevated oil temperature trigger rubber discoloration?
A: Specially stabilized raw material resists thermal discoloration; only faint surface dullness appears without dimensional change.
