HTG is a non-flammable, uncoated heat treated glass braided sleeve with a continuous operating temperature up to +220°C, but withstands short term peaks up to 600°C. It has a thermal classification of Class C and is available in sizes up to 25mm ID as standard.

This very flexible insulating braided jacket is made from thermally highly resistant E-glass which has been heat treated to prevent fraying and skin irritation. As no impregnants are used in the manufacture of this sleeve, compatibility with the majority of impregnation systems is also assured. It is suitable for use in any high temperature application as heat protection and reinforcement on cabling and wires. It is often used in furnaces and has been heat-treated.
