AeroFit Mechanical Grooved Insulation Fitting Covers


AeroFit™ Mechanical Grooved EPDM closed-cell fitting covers are engineered for quick installation on large 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 -- AC, REF™, ULP® and White/Gray.

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