Installation & Application Notes

Always match seal material to fluid type — NBR for petroleum, FKM (Viton) for high-temperature/chemical applications. Lubricate seals with clean fluid before fitting — never grease. Check shaft surface for scoring — rough surfaces destroy new seals within hours.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
