Braided Fiberglass Sleeve - Heat Treated - Expandable and Non-Expandable
High Temperature, Heat & Flame Resistant and Thermal Insulating
1200°F / 648°C Continuous Exposure: Higher Intermittent
DeltaGlass is a high temperature and heat resistant fiberglass sleeve is a braided fiberglass (fibreglass / glassfibre) sleeve, fabricated from high quality type E fiberglass that will not burn and will withstand continuous exposure to temperatures of 1200°F / 648°C.
It is further heat treated to remove loose fibers and to "set" the braid - making it easier to handle and install.
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. The base fiber is manufactured to the specifications of ASTM D-578, ASTM committee D13, and subcommittee D13.18. This product is 100% Asbestos free.
Available as an Expandable sleeve and as a Non-Expandable Sleeve. The difference is the braid angle - High braid angle results in an expandable sleeve - it can vary around the nominal size of the designated size of the sleeve - relaxed it expands and under tension the sleeve collapses smaller. Low braid angle results in a sleeve with minimal radial elasticity - maintaining its size under varying conditions of tension applied to the sleeve.
Available By-The-Foot and in Spool lengths. Minimum order value may apply to By-The-Foot quantities.
