G380PU Pump Seal for RC Engines - K285081290 by Zenoah  [K285081290]

Gasket Details for G380PU

The Zenoah K285081290 gasket is manufactured as a replacement seal for the G380PU pump assembly and comes without packing. It functions as the internal sealing element to preserve fuel containment and consistent pump output on nitro RC engines.

Replace the gasket during routine maintenance or when reassembling the pump after disassembly to recover correct pump characteristics. This helps maintain the prime and pressure profiles that influence carburetion and throttle response.

Installation notes:

• Ensure mating surfaces are free from residue or damage prior to installing the gasket.
• Swap the gasket whenever the pump is opened or if you detect seepage, since a worn seal undermines pump effectiveness.
• Place the gasket properly in the cavity and reassemble parts in their original orientation; avoid over-torquing fasteners.

Ideal for both field and bench work, this replacement gasket assists hobbyists in curing pump leaks, renewing seals, and preparing engines for running.
