Compression fittings for PEX

This category includes clamping screws designed for PEX (cross-linked polyethylene) pipe systems. These fittings are used in heating and plumbing applications where secure, leak-free connections are essential. The fittings are suitable for systems operating at a nominal pressure of PN 10 and temperatures up to +120°C. They are commonly used in radiant floor heating, domestic hot water systems, and other low-pressure hydronic applications.

The fittings are manufactured from brass CW617N and feature an EPDM O-ring for sealing. They are threaded with a Eurocone (EK) connection type, ensuring compatibility with standard PEX pipe fittings and systems.

How to choose

• Match the PEX pipe dimensions (e.g., 12 x 2, 16 x 2.2) to the fitting's internal diameter and wall thickness.
• Ensure the connection type is Eurocone (EK) for compatibility with PEX pipe systems.
• Verify the material (brass CW617N) and O-ring type (EPDM) are suitable for the intended operating conditions.
• Check the tightening torque range of 30–40 Nm for correct installation and sealing.
• Confirm the maximum operating temperature of +120°C is appropriate for the system.

Frequently asked questions

Can these clamping screws be used with PEX-a or PEX-b pipes?
Yes, they are suitable for PEX pipe systems provided the internal dimensions and wall thickness match the fitting specifications.

What is the recommended tightening torque for installation?
The tightening torque should be between 30–40 Nm to ensure a secure and leak-free connection.
