FAQ

Q：Can PTFE seal ring with minor scratches continue to be used?
A：Not recommended. Scratches form oil passage and cause internal leakage and clutch slip.

Q：Can I replace only this single white ring?
A：Not recommended. Other seals in the same group have aged, single replacement will lead to pressure loss again.

Q：What will happen if the seal ring twists during installation?
A：Uneven load causes rapid wear and pressure failure, shifting malfunction.

Q：Will new seal work if piston groove is worn?
A：Poor effect. Worn groove cannot hold the seal, internal leakage recurs quickly, repair or replace piston first.
