Zenoah K281714211 G450PU Insulator Gasket (W/O PACKING)  [K281714211]

G450PU insulation plate overview

This insulator gasket, part number K281714211 from Zenoah, fits G450PU engine assemblies and is supplied without packing as stated. It sits between mating engine parts to cut direct heat flow and to separate electrical contact paths where needed on nitro RC engines.

Fitting is straightforward for anyone familiar with basic engine teardown: separate the mating components, clean the sealing surfaces, lay the gasket flat, and reassemble using the engine's specified torque for studs or bolts. Since no packing is included, plan to source any sealing compound or extra gaskets before finishing the rebuild.

In regular maintenance and tuning the gasket helps stabilise thermal conduction at the joint and preserves consistent sealing after repeated disassembly, which supports steady valve timing and predictable engine behaviour during track or workshop adjustments.
