Aeroflex pipe insulations are designed to wrap around hot water pipes, that retard the flow of heat energy, to reduce energy losses. These pipe insulations feature EPDM rubber-based elastomeric construction to offer flexibility and UV resistance, thereby ideal for outdoor operations. They exhibit non-corrosive properties against copper and stainless-steel environments and require no additional vapour barrier. Designed to comply with ASTM E84 standards, for withstanding temperatures ranging from -297 to 300 degrees Fahrenheit, these insulations are available in 3/8, 3/4, 1/2 and 1 inch wall thickness options on Raptor Supplies.
