A plumbing pipe repair sleeve is a specially designed device used to cover, reinforce, and seal damaged or leaking sections of pipes. Typically made from durable materials such as stainless steel or high-density polyethylene, these sleeves can effectively clamp down around the damaged area, providing a waterproof seal that prevents further leakage. They are available in various sizes and designs to accommodate different pipe diameters and types, making them a versatile solution for many plumbing issues.
