Aerocel® Stay-Seal® with Protape® SSPT


Aerocel Stay-Seal with Protape SSPT pipe insulation has everything you would expect from a closed-cell elastomeric pipe insulation – flexibility, moisture resistance, low thermal conductivity and more. Plus, it has all the added convenience of a pre-slit dual tape closure for faster installation of the entire tube, including overlapping Protape seam closure, is made of EPDM rubber, providing users with superior condensation control and protection against moisture intrusion, UV and ozone. Our dual tape system includes pre-applied adhesive at the joined surfaces and the overlapping Protape for a more secure installation.

Available in tube sizes up to 16-inch IPS and 2-inch wall thickness. See data sheet for sizes, thicknesses, and corresponding R-values.

Available in Aerocel AC, ULP (Ultra-Low Perm), REF (Refrigeration), and White/Gray formulas.

Includes Cel-Link II® glueless seam seal technology! All SSPT pipe insulation shipments include Aeroflex’s revolutionary Cel-Link II glue-less seam seal solution. These patented “peel-and-seal” adhesive disks form bonds that are as strong as contact adhesive. Cel-Link II sheets are an easy-to-use, low-VOC alternative to contact adhesive. Installers may also use traditional contact adhesive for bonding butt joints and termination points.
