AeroFit™ EPDM Insulation Fitting Covers


AeroFit fitting covers are prefabricated for fast, high-quality installation over mechanical grooved fittings, elbows, tees and P-traps. Factory fabrication reduces installation costs and helps conserve energy by preventing heat gain/loss. AeroFit covers also improve aesthetic appearance of installation and reduce the probability of corrosion under insulation (CUI).

Available in a wide variety of thicknesses in popular I.D. sizes up to 6-inch IPS. Each fitting is prefabricated from AEROFLEX® Black and White/Gray closed-cell pipe insulation for seamless EPDM durability, low thermal conductivity and UV-resistance.

See data sheet for available sizes and thicknesses.
