Water Pipe Insulation Sleeve Self Adhesive Foam Tube, Aluminum Foil Covers for Spigot, Winter Outside Pipes, Sprinkler(ID*TH 27*40mm/1.06*1.57in). The inner diameter of the insulation sleeve corresponds to the pipe's outer diameter. Measure the pipe diameter first and select the appropriate size specification. The insulation pipe features a pre-cut design—simply clamp it onto the pipe, peel off the adhesive backing, and wrap it around the pipe. The self-adhesive film design prevents adhesive peeling, ensuring a secure hold. The aluminum foil layer provides superior protection against sunlight and heat radiation, offering better insulation performance than standard non-aluminum foil insulation tubes. The closed-cell foam structure is waterproof, fire-resistant, wear-resistant, and sound-absorbing.
