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

G380PU Gasket Description

The K285081290 pump gasket from Zenoah is an aftermarket replacement designed for the G380PU pump assembly and is supplied without any packing. It sits inside the pump housing to maintain fluid containment and consistent pump performance on nitro-powered RC models.

Install this gasket during scheduled service intervals or when restoring the pump after teardown to reestablish correct pumping characteristics. It contributes to preserving prime and pressure behaviour that affect fuel delivery and throttle response.

Installation notes:

• Inspect and clean mating surfaces to remove oil and debris before fitting the new gasket.
• Replace the gasket whenever the pump is opened or leakage is evident, as aged seals will reduce pump efficiency.
• Make sure the gasket is seated correctly in the cavity and reassemble parts in their original placement; do not overtighten screws.

Well suited to both field repairs and bench servicing, this gasket helps modelers eliminate leaks, refresh seals, and prepare engines for running.
