Conex PRESS GAS coupling MUFA 22 for gas installations, 22 mm

Conex PRESS GAS coupling MUFA 22 is a press-fit coupling intended for gas installations with a 22 mm nominal pipe diameter. Designed for indoor gas distribution systems in residential and commercial buildings, this coupling creates a mechanical pressed joint between two sections of gas pipe. It is compatible with Conex press tools and fittings and is engineered to provide a reliable, low-leakage connection when installed according to applicable gas installation standards.

Advantages

The press-fit design eliminates the need for open flame or soldering, reducing installation time and improving site safety. Constructed from materials suitable for gas applications, the coupling offers consistent joint quality when used with the correct press profile and tooling. Its compact form factor supports installations in confined spaces and contributes to a neat, durable piping system with reduced risk of joint failure compared with some traditional joining methods.

Suitable for

• Indoor gas distribution in residential buildings
• Commercial gas piping systems
• Connections between 22 mm gas pipes in renovation and new-build projects
• Situations requiring fast mechanical joints without soldering

Key specifications

• Nominal pipe size: 22 mm
• Connection type: press-fit coupling for gas systems
• Application area: indoor gas installations (residential and commercial)
• Compatibility: compatible with Conex press tools and press fittings designed for gas
• Installation method: mechanical pressing with appropriate press jaws or sleeves

How to use

Prepare pipe ends by cutting square and removing burrs, ensuring pipes are clean and free from oil or debris. Slide the coupling onto the pipe ends until fully seated and aligned. Use the recommended Conex press tool and the correct gas press profile or jaw set to perform the press operation, following the tool manufacturer’s instructions and applicable gas installation codes. Verify each pressed joint visually and, where required, perform pressure testing in accordance with local regulations to confirm leak-tightness before commissioning the system.

Usage recommendations

Use only approved press tools and jaws compatible with Conex gas press fittings, and follow local gas installation standards. Ensure all personnel performing installation are trained in press-fit gas systems and that completed installations undergo required pressure and leak tests prior to energising the gas supply.
