This set of pipe insulation foam tubes includes 12 black foam tubes, each measuring 1 meter (3.28 ft) long, with an outer diameter of 42 mm (1.65 in), inner diameter of 22 mm (0.87 in) and thickness of 10 mm (0.39 in), designed to fit 3/4 in. copper pipes. Made from high-quality PEP foam, the insulation is soft, durable, resistant to tearing and wear, and offers reliable anti-collision protection while being reusable for long-term use. It features fireproof, heat insulating and sound absorbing properties, with good elasticity that allows easy bending for safe, straightforward application. The pre-slit design simplifies installation, as users can simply clamp the foam directly onto pipes for a secure, firm fit that stays in place. Additionally, the foam is waterproof, dustproof, oil-resistant and corrosion-resistant, making it ideal for insulating various outdoor pipes to prevent freezing in winter, as well as for protecting winter irrigation systems, sprinklers and faucets.
