AEROFLEX EPDM™ Unslit Tube

Description

Aeroflex® Unslit EPDM Pipe Insulation is a closed-cell, flexible elastomeric foam insulation designed to slide easily over new piping installations or can be slit to snap over existing piping. With a built-in vapor retarder, this EPDM insulation provides long-lasting thermal performance and superior environmental stability. Ideal for HVAC, VRF, chilled water, refrigeration, and hot/cold water piping applications, it offers durability, moisture resistance, and excellent UV protection for both indoor and outdoor use.
