AeroFit Mechanical Grooved Insulating Fitting Covers


AeroFit™ Grooved Mechanical closed-cell fitting covers are engineered for quick installation on piping systems insulated with Aerocel® closed-cell elastomeric foam insulation. Made with the same proprietary EPDM-based formula as other Aerocel insulations, AeroFit covers help maintain the seamless integrity of your non-polar 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 all Aerocel EPDM closed-cell elastomeric foam formulations -- Black, White/Gray, Ultra-Low Perm (ULP) & Refrigeration (REF)

Wide range of ID’s (½”- 6” IPS) and thicknesses (½” – 1½”)
