Copper 45° Double-Socket Elbow SANHA SANHA-Therm ZWxZW 22

The SANHA-Therm 45° double-socket elbow ZWxZW 22 is a copper fitting engineered for creating compact angled connections in copper piping systems. It provides a 45° change in direction with two compatible sockets for joining standard 22 mm copper tubes. The fitting is suitable for use in heating circuits, potable water installations and certain gas systems where copper piping and socket-type connections are specified. The design allows installation by press systems or capillary soldering, depending on project requirements and local codes.

Advantages

The copper construction ensures good thermal conductivity and durability while remaining corrosion-resistant in normal water and heating environments. Dual sockets sized for 22 mm tubing provide consistent alignment and a tight mechanical fit for reliable joints. Compatibility with both press and capillary soldering methods gives installers flexibility, enabling faster press connections or traditional soldered joints where preferred. The compact 45° form factor reduces occupied space compared with larger radius fittings and simplifies routing in confined installations.

Suitable for

• Domestic and commercial heating systems with copper pipework
• Drinking water distribution lines using copper tubing
• Plumbing runs requiring compact angled changes in direction
• Installations where press fitting or capillary soldered sockets are used

Key specifications

• Material: Copper
• Angle: 45°
• Connection type: Double socket (ZWxZW) compatible with press or capillary soldering
• Nominal tube size: 22 mm
• Application areas: Heating, potable water, compatible gas systems where copper is allowed

How to use

Select the appropriate jointing method (press or capillary soldering) according to the installation standards and local regulations. Prepare and deburr the ends of the 22 mm copper pipes to ensure proper fit. For capillary soldering, clean and flux the tube and socket, assemble the joint fully and apply heat to achieve a capillary bond following recommended soldering practice. For press installations, insert the prepared tube into the socket until it reaches the stop, and operate the compatible press tool and jaw to form the mechanical connection. After joining, inspect each joint for alignment and, if applicable, perform pressure testing as required.

Usage recommendations

Use appropriate personal protective equipment during soldering and pressing. Verify compatibility of the fitting with the system medium and local codes before installation. Follow manufacturer guidance for press tooling and solder materials to ensure reliable, code-compliant joints.
