TGFx Thermal Gap Fillers

LeaderTech TGFx Thermal Gap Fillers are a reliable heat transfer media that fill air gaps by conforming to surface gaps and irregularities. The Thermal Gap Fillers also conduct heat from a heat source to another surface. Available in various shapes, sizes, and thermal conductivities, thermal gap fillers offer a cost-effective solution for some of the most difficult and delicate thermal situations in a broad spectrum of applications.
