KAN-therm mufa 28x28 X Steel Press pipe coupling 28×28 mm

KAN-therm mufa 28x28 X Steel Press pipe coupling 28×28 mm is a steel press fitting designed to join two 28 mm pipes with a secure press-fit connection. Intended for plumbing and heating installations, the fitting forms a mechanical joint when compressed with compatible press tools and seals. Its steel construction provides strength and dimensional stability for water and heating circuits where press technology is specified.

Advantages

The steel press coupling offers a durable mechanical connection that resists deformation under typical operating pressures and temperatures found in domestic and commercial heating and water systems. Press installation reduces assembly time compared with traditional soldering or threaded joints and eliminates the need for open flames. When used with appropriate O-rings and certified pressing tools, the coupling provides a tight seal and consistent joint quality across multiple installations.

Suitable for

• Joining two 28×28 mm metal pipes in hot and cold water systems
• Connections in central heating and radiator circuits
• Replacement or repair of existing press-fit piping segments
• Installations where flame-free joining methods are required

Key specifications

• Material: steel construction for structural strength
• Connection method: press-fit compatible with press tooling
• Nominal size: 28 × 28 mm pipe ends
• Application medium: potable water and heating media
• Operating environment: indoor plumbing and heating systems

How to use

Ensure both pipe ends are cut square, deburred and cleaned of any contaminants. Fit the appropriate elastomeric seals or O-rings into the coupling as required by the press system manufacturer. Position the coupling over the pipe ends so that the marking or stop indicates correct insertion depth. Use a compatible press tool with the correct jaw or ring size for 28 mm steel press fittings and perform the press operation following the tool manufacturer's instructions. After pressing, verify the joint visually and, if applicable, pressure-test the system to confirm leak-tightness.

Usage recommendations

Use only compatible seals and certified press tools sized for 28 mm steel fittings. Avoid using the coupling in environments with aggressive chemicals or external corrosion unless additional protection is applied. Follow local regulations and standards for potable water and heating installations, and perform pressure testing after installation to ensure system integrity.
