SANHA SANHA-Therm 45° double-socket elbow ZW×ZW 28 mm

SANHA SANHA-Therm 45° double-socket elbow ZW×ZW 28 mm is a 45-degree copper socket fitting designed for creating sealed joints in heating and potable water pipework. The fitting accepts 28 mm tubes at both ends and provides a stable directional change where a slight angle is required. It is intended for use with SANHA-Therm compatible copper or similar tube systems in residential and light commercial plumbing and heating installations.

Advantages

The elbow offers a compact 45° change of direction with two socket connections that ensure reliable, leak-resistant joints when installed according to accepted soldering or brazing practice. Its copper construction provides good thermal conductivity and corrosion resistance suitable for hot water and heating circuits. The double-socket design simplifies alignment and reduces the need for additional coupling components in confined spaces.

Suitable for

• Changing pipe direction in heating systems
• Potable water supply installations
• Residential and light commercial plumbing projects
• Repair or rerouting of existing copper pipelines

Key specifications

• Angle: 45°
• Connection type: double socket (ZW × ZW)
• Nominal tube diameter: 28 mm
• Material: copper (SANHA-Therm compatible)
• Application: heating and potable water systems

How to use

Prepare tube ends by cutting square, deburring, and cleaning the inside and outside of the pipe and the socket surfaces. Assemble the tubes into the sockets to the correct depth to ensure full engagement. Make the joint by applying the appropriate flux and using soldering or brazing methods recommended for copper fittings and the specific heating or potable water system. After cooling, inspect the joint for continuity and perform a pressure test according to installation standards.

Usage recommendations

Follow local plumbing codes and manufacturer installation instructions. Use suitable flux and filler materials compatible with copper and potable water systems, and ensure joints are accessible for inspection and pressure testing before putting the system into service.
