Pipe Elbow 45° Uponor PPSU 50 x 50 mm

Uponor Pipe Elbow 45° PPSU 50 x 50 mm is a 45-degree plumbing fitting manufactured from PPSU (polyphenylsulfone) designed to join two 50 mm pipes with a smooth change of direction. Intended for use in potable water and central heating systems, the fitting offers high temperature and chemical resistance together with long-term dimensional stability. The elbow provides a compact solution for rerouting pipe runs where space constraints or specific routing requirements call for a gradual angle rather than a sharp turn.

Advantages

The PPSU construction combines mechanical strength with resistance to hot water, steam and many common chemicals, reducing the risk of deformation and leaks over time. The 45° angle minimizes flow disturbance compared with sharper fittings, helping to maintain hydraulic efficiency in heating and plumbing circuits. Corrosion resistance and compatibility with potable water standards support use in domestic and commercial installations, and the precision moulded geometry ensures consistent fit and reliable jointing with compatible 50 mm system components.

Suitable for

• Potable water distribution systems requiring durable, non-corroding fittings
• Central heating circuits where temperature resistance and stable joints are needed
• Plumbing layouts with limited space that need a 45° change of direction between 50 mm pipes
• Systems exposed to chemicals or higher temperatures where metal fittings are undesirable

Key specifications

• Angle: 45° change of direction
• Material: PPSU (polyphenylsulfone)
• Connection size: 50 x 50 mm
• Application: potable water and central heating systems
• Temperature resistance: suitable for high-temperature hot water applications (see system design limits)
• Corrosion resistance: non-metallic, resistant to corrosion and many chemicals

How to use

Install the elbow in accordance with the Uponor system instructions and industry best practice. Ensure pipe ends are clean, cut squarely and deburred before making the joint. Fit the 50 mm pipes into the elbow until the reference depth is reached; use the recommended joining method for the specific Uponor 50 mm system (for example press-fit, socket fusion or approved mechanical connection) and verify each joint for correct engagement. After assembly, perform pressure and leak tests as required by local regulations and system specifications.

Usage recommendations

Use this 45° PPSU elbow in combinations with compatible Uponor 50 mm components and follow manufacturer guidelines for working temperatures and pressure limits. Avoid exposure to unsupported mechanical loads or continuous UV exposure; store and install in conditions that meet the system’s temperature and chemical compatibility requirements.
