Zenoah K285081290 Pump Gasket for G380PU (without packing)  [K285081290]

Pump gasket for G380PU

This Zenoah pump gasket K285081290 is an RC-scale replacement seal designed for the G380PU pump assembly, supplied without packing material. It serves as the interface seal inside the pump housing to maintain fluid containment and consistent pump behaviour on nitro RC engines.

Use this gasket when performing routine pump maintenance or when restoring proper pump operation after disassembly. The part is intended for hobby-scale engine pump systems and assists in preserving prime and pressure characteristics that affect carburetion and throttle response.

Installation notes:

• Inspect mating surfaces for residue or damage before fitting the gasket.
• Replace the gasket whenever the pump is opened or if leaks are detected, as a worn seal can degrade pump performance.
• Ensure correct seating in the pump cavity and reassemble components in original orientation, avoiding overtightening fasteners.

The item is straightforward for field service or bench maintenance and is useful for hobbyists managing pump leaks, restoring seals, or preparing engines for track sessions.
