SANHA SANHA-Therm 90° elbow fitting (zwxzz) 35 mm

The SANHA SANHA-Therm 90° elbow fitting (zwxzz) 35 mm is a 90-degree copper/alloy elbow designed for heating and plumbing systems. It provides a compact right-angle change of direction between two pipes with a 35 mm nominal diameter. The fitting is intended for installations where a reliable, low-profile elbow connection is required in residential and commercial piping networks.

Advantages

This 90° elbow offers corrosion-resistant copper-alloy construction suitable for hot water and heating circuits, ensuring long-term dimensional stability and leak-tight joints when installed according to industry standards. Its 35 mm size matches common pipe dimensions used in medium-capacity heating systems and sanitary installations. The zwxzz configuration enables a simple right-angle connection while maintaining smooth internal flow to minimise pressure loss.

Suitable for

• Domestic hot water distribution and central heating circuits
• Commercial plumbing installations and service risers
• Directional changes in copper or compatible alloy piping systems
• Replacement or retrofit of existing 35 mm elbow sections

Key specifications

• Angle: 90 degrees
• Nominal diameter: 35 mm
• Material: copper or copper-alloy (suitable for thermal and potable water systems)
• Connection type: zwxzz right-angle elbow configuration
• Typical applications: heating, hot water, plumbing installations

How to use

Prepare the pipe ends by cutting square and removing burrs, then clean mating surfaces according to the chosen joining method and applicable codes. Fit the elbow onto the prepared pipes ensuring correct alignment at 90 degrees. Join the connection using the appropriate technique for copper/alloy fittings (e.g., soldering, brazing, or approved press method) following manufacturer and local installation standards. After joining, allow the joint to cool as required and perform pressure and leak tests to verify installation integrity before placing the system into service.

Usage recommendations

Use compatible pipe material and approved joining methods for the SANHA-Therm elbow, and follow local regulations for installation and pressure testing. Avoid mechanical stress on the joint by supporting adjacent piping and maintain access for future inspection.
