Thermosleeve B Glass Fiber Sleeve




Heavy wall braided glass fiber sleeve: economical hose and cable protection where exposure to molten splash, oils or moisture is not a factor.

Cost-efficient high temperature performance

Thermosleeve™ B is a heavy wall braided glass fiber sleeve capable of operating at a continuous temperature of 1000°F (538°C). High bulk fiber construction gives excellent insulation properties, and the texturized, untreated construction allows Thermosleeve ™ B to exhibit excellent dielectric strength and a low thermal conductivity.

Use alone or in combination

Thermosleeve™ B can be used by itself, or under other sleeve products (such as Pyrojacket®, Pyreflect™ or  Silicaflex™) to significantly boost insulation values at modest cost.

Choice of grades

Thermosleeve ™ B is available in 2 grades: 1/8″ (3.2 mm) wall thickness or 1/16″ (1.6 mm) wall thickness.
