O.S. Engine OS49469450 Thermo Insulator GF40 Flexible Thermal Sheet for R/C Engine Accessories  [OS49469450]

Heat-shielding sheet for R/C engines

The O.S. Engine OS49469450 Thermo Insulator GF40 is an RC-scale thermal insulation sheet designed for use with R/C engine accessories and maintenance tasks. It fits between hot components and nearby parts to moderate heat flow, helping the engine and surrounding items keep steadier temperatures during operation and when stored or transported.

This item is a lightweight, thin sheet that can be trimmed to sit around cylinder heads, muffler flanges, or intake areas without adding noticeable bulk. Its value is practical: by reducing heat soak to adjacent components, it supports more consistent engine behaviour and simplifies temperature-related tuning.

Fitting is simple on common R/C engine layouts. Cut the sheet to the required shape, hold it in place with existing clamps or removable tape as needed, and ensure vents and exhaust routes remain clear. Check the material periodically for compression or oil contamination that might reduce insulating effectiveness and replace if it shows wear.

Compatibility is general across R/C engine accessories rather than specific chassis models, so visually confirm fitment before final installation. Use this product only on model engines and their associated components.
