SANHA 90° double-socket elbow SANHA-Therm ZWxZW 42 for sanitary/heating installations

SANHA 90° double-socket elbow SANHA-Therm ZWxZW 42 is a press-fit fitting designed for sanitary and heating installations. The fitting has two female (socket) ends with a 42 mm nominal diameter and provides a reliable 90° change of direction between two press-type pipes. It is intended for use with compatible metal or press-compatible pipes in potable water systems, closed heating circuits and other installations that require press connections.

Advantages

The SANHA-Therm 90° double-socket elbow offers a compact geometry that minimizes space requirements at pipe junctions and ensures stable axial alignment of connected pipes. Press-fit joining provides a reproducible, leak-resistant connection without the need for soldering or welding, reducing installation time and on-site heat exposure. The product is manufactured to industry standards for materials and dimensions appropriate to sanitary and heating systems, enabling compatibility with common press tools and seals used in professional plumbing.

Suitable for

• Potable water distribution in residential and commercial buildings
• Closed heating circuits such as radiator and underfloor heating systems
• Sanitary installations where a 90° directional change is required
• Systems using press-fit metal or press-compatible pipes

Key specifications

• Connection type: double female (socket) press-fit
• Angle: 90° elbow
• Nominal diameter: 42 mm
• Application: sanitary and heating installations, potable water and closed heating circuits
• Joining method: press connection for use with compatible press tools and rings

How to use

Prepare pipe ends by cutting square and deburring the inner and outer edges. Slide the appropriate press-fit sealing element or ring onto the pipe according to the seal manufacturer’s instructions, then fully insert the pipe into each socket until it reaches the fitting’s stop. Use a compatible press tool and jaws sized for 42 mm press fittings to perform the press joint at each socket, ensuring the tool is centered and the pressing cycle is completed. After pressing, inspect each joint for correct deformation of the press ring and verify there are no visible gaps.

Usage recommendations

Confirm compatibility of pipe material, press seals and press tool before installation. Follow local plumbing standards and manufacturer guidance for pressure testing and system commissioning. Avoid applying open flame near the fitting and ensure connections are installed by trained personnel or qualified plumbers.
