Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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

Failure Symptoms

The first sign of failing O-rings is often a visible fluid leak around a connection or component. If left unaddressed, the leak will likely worsen, leading to a gradual loss of system pressure and potentially affecting the performance of the equipment. Significant fluid loss can compromise system operation and lead to component damage.

Installation Tip

Ensure the sealing groove is clean and free of debris before installing a new O-ring; avoid using sharp tools that could nick or cut the seal. Lubricate the O-ring and the groove lightly with a compatible lubricant before installation to prevent damage during seating.

Service Note

When replacing O-rings, inspect the mating surfaces for any damage or wear that could prevent a proper seal.
