The pressure rating of water pipe fittings varies depending on the fitting type, material and manufacturer specification. Many fittings used within water supply systems are designed to handle high-pressure applications commonly found in mains and service pipe installations.
What Size Water Pipe are They Suitable for?
Water pipe fittings are available in a wide range of sizes to suit different pipe diameters and applications. Common sizes include 20mm, 25mm, 32mm, 63mm and larger utility-scale options.
Are Water Pipe Fittings Suitable for Existing Pipe Systems?
