O.S. Engine OS4A404160 Head Gasket 0.2T GGT10 engine head gasket for RC nitro models  [OS4A404160]

Head gasket for RC nitro engines

This O.S. Engine head gasket provides a thin 0.2T sealing option for RC-scale nitro engines that accept GGT10-series gaskets. It is intended as a service part for engine builders and tuners who need a precise shim to adjust combustion chamber volume and sealing between the cylinder head and liner.

Installation notes: clean mating surfaces, inspect the head and liner faces for flatness, and replace the gasket whenever head hardware is removed or when sealing performance degrades. Use the gasket as part of controlled tuning—changing gasket thickness alters compression ratio slightly, which can affect idle and midrange response on nitro models.

Tuning role: as a 0.2T option this gasket suits fine adjustments where a minimal reduction in combustion volume is desired compared with thicker gaskets, helping to dial in starting and throttle response without altering major engine components.
