AeroFit™ EPDM Mechanical Grooved Insulation Fitting Covers


AeroFit Mechanical Grooved EPDM closed-cell fitting covers are engineered for quick installation on large piping systems insulated with AEROFLEX EPDM closed-cell elastomeric foam insulation. Made with the same proprietary EPDM-based formula as other Aeroflex insulations, AeroFit covers help maintain the seamless integrity of your nonpolar EPDM insulating system.

Precise factory fabrication saves field labor and improves the overall aesthetics of installation for these complex applications. Ensures consistent, long-lasting thermal performance and protection against moisture and environmental stresses.

Available in Black and White/Gray AEROFLEX® formulations.

Wide range of ID’s (½”- 6” IPS) and thicknesses (½” – 1½”). See data sheet for more details.
