This high temperature and heat resistant fiberglass sleeve is a braided fiberglass (fibreglass) sleeve, fabricated from high quality type E fiberglass that will not burn and will withstand continuous exposure to temperatures of 1000° F / 520° C. It provides excellent protection for wires, cables, hoses, tube and pipes and also provides thermal insulation and personnel protection.

This high temperature sleeve / heat resistant sleeve resists most acids and alkalis and is unaffected by most bleaches and solvents. It is highly flexible and conformable.

Fiberglass offers excellent heat resistance, retaining more than half of its room temperature tensile strength at 675° F / 357° C, and more than 25% at 875° F / 468° C. It begins to soften at 1500° F / 815° C and melts near 2050° F / 1121° C. Non-combustible and excellent thermal conductivity to dissipate hot spots; high resistance to chemicals and unaffected by UV light.
