Protect your outdoor pipes from freezing temperatures with this self-adhesive foam insulation tube. It has an inner diameter of 34mm (about 1-1/4 inches) and comes in a 1-meter length. The foam is covered with a reflective aluminum foil surface that helps trap heat and reflects sunlight, and it has a self-adhesive seam so you can wrap it easily around pipes. It's waterproof, flame-retardant, and flexible enough to fit bends and joints. Perfect for water pipes, backflow preventers, sprinkler systems, pool filters, and well pumps. Just peel off the backing, wrap it around your pipe, and press it closed. Really helps prevent bursts in winter and can also reduce condensation in summer. Check your pipe's outer diameter before ordering to ensure a snug fit.
