Tubular sleeves can also be used on small diameter bends, reducers,socket joint shapes,couplings,flanges.casings,tyton joints,step-down joints, and as protection of anchor tie rods.
Construction
First layer: Mastic elastic low preheat sealant adhesive.
Second layer: Radiation cross-linked, high density polyethylene.
Features & Benefits
• No primer required.
• Low preheat sensitivity & proven high functionality.
