PERT, or Polyethylene of Raised Temperature resistance, is a type of plastic pipe known for its exceptional flexibility and durability, even at high temperatures. Unlike standard polyethylene, its molecular structure is engineered to resist thermal degradation, making it an excellent choice for hot and cold water applications. Its key advantage is its ability to be easily bent, significantly reducing the need for elbow fittings and joints, which speeds up installation and minimizes potential leak points.
