G380PU Pump Gasket Replacement (without packing) - K285081290 by Zenoah  [K285081290]

G380PU Pump Gasket Overview

This Zenoah pump gasket K285081290 is an RC-scale replacement seal designed for the G380PU pump assembly, supplied without packing material. It forms the internal seal in the pump housing to maintain fluid containment and steady pump behaviour on nitro RC engines.

Fit this gasket when carrying out routine pump service or when restoring correct pump function after disassembly. The part supports hobby engine pump systems by helping preserve prime and pressure traits that influence carburetion and throttle response.

Installation notes:

• Check mating surfaces for residue, nicks, or abrasions before fitting the new gasket.
• Replace the gasket whenever the pump is opened or if you detect leakage, since a degraded seal will reduce pump performance.
• Seat the gasket correctly in the pump cavity and reassemble components in their original orientation; avoid overtightening fasteners.

The component is suitable for simple field service or bench work and is handy for hobbyists addressing pump leaks, renewing seals, or preparing engines for running.
