This metric O-ring kit contains a variety of essential seals used throughout the engine and hydraulic systems to prevent leaks. Manufactured from durable materials, these O-rings provide a reliable seal replacement for worn or damaged originals. Leaking O-rings can lead to fluid loss, reduced system pressure, and contamination, manifesting as visible drips or reduced equipment performance.

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 most common symptom of failing O-rings is visible fluid leakage at connection points. If left unaddressed, this can lead to a gradual loss of system pressure and fluid levels, potentially causing component damage or operational failure. Persistent leaks can also lead to environmental contamination and safety hazards.

Installation Tip

Lightly lubricate O-rings with the appropriate system fluid before installation to prevent tearing. Ensure the sealing surfaces are clean and free from burrs or damage.

Service Note

Inspect all associated seals, hoses, and fittings for wear or damage when replacing O-rings.
