Compression coupler SANHA SANHA-Therm Mufa ZWxZW 22 — SANHA 22 mm

SANHA-Therm Mufa ZWxZW 22 — SANHA 22 mm compression coupler is designed for reliable mechanical connections in heating and plumbing installations. The product creates a press-fit joint between compatible 22 mm copper or press-fit pipes and fittings, providing a sealed connection suitable for potable water systems, heating circuits and radiator connections. It is intended for use where a durable, low-profile joint with consistent sealing performance is required.

Advantages

The compression coupler offers a compact design that simplifies installation in confined spaces and enables a secure, leak-resistant joint without soldering or threading. Its press-fit operation reduces installation time and minimizes the need for additional sealing materials. The coupler is compatible with standard 22 mm press systems and is suitable for permanent mechanical connections in both domestic and commercial heating and plumbing applications.

Suitable for

• Connections of 22 mm copper or press-fit pipes
• Domestic and commercial heating circuits and radiator connections
• Potable water distribution systems
• Repairing or modifying existing press-fit piping networks

Key specifications

• Connection type: 22 mm press-fit compression coupler
• Application: heating systems, potable water, radiator connections
• Material compatibility: copper and compatible press-fit pipes and fittings
• Installation method: press-fit (mechanical pressing), no soldering required
• Design: compact, low-profile for tight spaces

How to use

Prepare pipe ends by cutting square and deburring inner and outer edges. Insert pipe fully into the coupler until it seats against the stop. Verify alignment and ensure the sealing element is correctly positioned. Use an appropriate pressing tool and the correct jaw size for 22 mm connections to perform the press operation according to the tool manufacturer's instructions. After pressing, inspect the joint visually and, if required, perform a pressure test in line with local regulations and project specifications.

Usage recommendations

Store fittings in a dry, dust-free environment prior to installation and protect pressed joints from mechanical damage and prolonged UV exposure. Follow applicable standards and manufacturer guidelines for press equipment, testing pressures and service media. For assemblies on potable water systems, ensure all materials and installation practices comply with local drinking water regulations.
