Aeroflex Aerofix Hanger Blocks



Aerofix patented insulated pipe supports provide seamless, EPDM thermal performance and zero-perm moisture resistance without worries of insulation compression and thermal bridging at hanger locations.

A rigid, polymeric core is lined with closed-cell EPDM foam rubber and encased with a zero-perm, weather-proof and corrosion-proof EPDM membrane. A built-in, self-seal Aeroflex Protape® closure ensures seamless EPDM protection and fast installation.

Each self-contained, three-piece assembly is zero-perm, resistant to UV degradation, condensation, and heat gain. Suitable for continuous service temperatures ranging from -328°F to 257°F (-200°C to 125°C). May be used with trapeze (strut), split-ring, clevis, roller, clamps, and straphangers.

Available in a wide range of pipe diameters and thicknesses up to 300mm IPS and 50mm wall thickness. See data sheet for more details.
