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

Insulator gasket for G450PU

This insulator gasket is an RC-scale replacement part labelled K281714211 for use with G450PU engine assemblies, supplied without packing as noted in the part name. It serves as the interface layer between mating engine components to reduce direct heat transfer and separate electrical contact paths where applicable on nitro RC engines.

Installation is straightforward for hobbyists familiar with basic engine disassembly: remove the mating components, clean sealing faces, position the gasket flat and reassemble with correct torque values for the engine studs or bolts. Because the item is supplied without packing, check that any required sealing compound or additional gaskets are sourced separately before reassembly.

In tuning and maintenance the gasket’s role is to stabilise thermal conduction at the interface and help maintain consistent sealing under repeated teardown, which aids valve timing stability and overall engine consistency when performing adjustments trackside or during workshop servicing.
