Compression coupling SANHA SANHA-Therm Mufa ZWxZW 35 for copper and composite pipes, 35 mm

SANHA-Therm Mufa ZWxZW 35 is a compression coupling by SANHA for 35 mm copper and composite pipes, engineered for plumbing and heating installations. The fitting creates a mechanical, leak-resistant connection without the need for soldering or welding, enabling fast assembly and secure joints in potable water systems, heating circuits and general sanitary applications. The coupling is suitable for repairs, system extensions and new installations where a push-fit, compression-style connection is preferred.

Advantages

The compression coupling offers a reliable, tool-assisted method for joining copper and composite pipes with consistent sealing performance. Installation does not require flame or flux, reducing on-site hazards and preparation time. The design provides a compact connection with low profile and good mechanical strength, making it convenient in confined spaces. It is compatible with common pipe materials in modern plumbing and heating systems and supports potable water and heating media when fitted according to installation rules.

Suitable for

• Joining 35 mm copper pipes in heating and potable water systems
• Connecting 35 mm composite (multi-layer) pipes
• Repairing leaks and replacing short pipe sections
• System extensions and retrofit installations
• Applications where solder-free connections are required

Key specifications

• Nominal pipe diameter: 35 mm
• Applicable pipe materials: copper and composite (multi-layer) pipes
• Connection type: compression coupling (push-fit compression joint)
• Intended media: potable water and heating fluids
• Installation method: mechanical assembly without soldering

How to use

Prepare the pipe ends by cutting square and deburring inner and outer edges to ensure proper seating. Slide the coupling components onto the prepared pipe ends and insert pipes fully into the fitting until they reach the internal stop. Tighten the compression nuts to the specified torque or until the manufacturer’s recommended compression is achieved, ensuring the sealing elements engage evenly. Verify alignment and clearance, then pressure test the assembled joint according to applicable standards and local regulations before putting the system into service.

Usage recommendations

Use only on pipes of the specified 35 mm nominal diameter and compatible materials. Follow local plumbing codes and SANHA installation guidelines for permitted media, maximum operating pressures and temperatures. Inspect sealing elements before assembly and replace any damaged components. For exposed installations, consider appropriate support and protection against mechanical damage and thermal expansion.
