GF40 Thermo Insulator Sheet for R/C Engines - O.S. Engine OS49469450  [OS49469450]

Thermal protection for model engines

The O.S. Engine OS49469450 Thermo Insulator GF40 is an insulation sheet sized for R/C engine accessories and workshop use. Positioned between heat sources and nearby parts, it reduces direct heat transfer to aid steadier temperatures during use and transit.

Supplied as a slim, lightweight sheet, it is simple to trim to fit around cylinder heads, muffler flanges or intake areas without adding bulk. Its benefit is stability rather than a performance boost: by reducing heat soak to adjacent components it supports more predictable engine behaviour and easier temperature-related adjustments.

Installation is straightforward on typical R/C engine layouts. Cut to the required profile, hold it in place with clamps or removable tape as appropriate, and ensure vents and exhaust paths stay clear. During routine checks look for oil contamination or compression that might reduce insulating effectiveness and replace if necessary.

This insulator is generally compatible with a wide range of R/C engine accessories rather than specific chassis lines, so verify fitment visually before permanent attachment. Use only with model engines and associated parts.
