Straight press couplings - PPSU

This category includes direct press couplings made from PPSU (polyphenylsulfone) for connecting ALPEX pipes of equal diameter. These fittings are designed for use in heating and plumbing systems operating at a maximum temperature of +120 °C. The couplings feature a stainless steel sleeve and an EPDM sealing ring to ensure a durable and leak-free connection. They are suitable for press-fit installation using approved pressing tools and are commonly used in residential and commercial building projects.

The fittings are available in various sizes to match standard pipe dimensions, ensuring compatibility with existing system layouts. They are ideal for applications where a direct connection between two pipes is required without the need for additional adapters or transitions. These couplings are commonly used in underfloor heating, domestic hot water systems, and industrial piping where high thermal resistance and chemical stability are essential.

How to choose

• Confirm the pipe diameter to ensure the coupling matches the same size on both ends.
• Verify the material compatibility of the coupling with the ALPEX pipe and system operating conditions.
• Check the maximum operating temperature of +120 °C to ensure suitability for the application.
• Ensure the pressing tool is compatible with the coupling’s design for a secure fit.
• Confirm the presence of a stainless steel sleeve and EPDM gasket for long-term sealing performance.

Frequently asked questions
