50ST Engine Insulator Gasket YS Engine YSS1024 for RC Glow Engines  [YSS1024]

Thermal spacer for 50ST glow engines

This YS Engine YSS1024 insulator gasket is an accessory made for 50ST-type glow engines used in radio control models. It acts as a thin insulating spacer between the engine flange or head and the mounting structure to reduce direct heat conduction and assist with retaining correct head alignment.

Fit the gasket where combustion heat and engine vibration can influence mounting geometry; the isolator reduces heat transfer to the mount and helps damp minor vibration. Check mating surfaces for flatness and cleanliness before installation to ensure an even seal and consistent contact.

Installation advice: place the gasket between the engine flange and the mount or between the cylinder head and backplate as needed by your setup, tighten fasteners evenly to avoid uneven compression, and re-check alignment after an initial run. This is a small, lightweight part intended for mounting adjustment and thermal isolation on model glow engines.
