PRESS wall - through, 16 x 1/2" F

Product detailed description

This press wall fitting is used in residential and commercial buildings for connecting ALPEX pipes in heating and plumbing systems. It provides a compact and reliable connection solution in tight spaces, such as walls and ceilings. Installers commonly use it in underfloor heating, domestic hot water, and central heating applications where space constraints require wall-mounted connections. The fitting ensures a secure and leak-free connection while maintaining compatibility with standard ALPEX pipe systems.

The press wall fitting is ideal for systems where the pipe must pass through a wall or partition. It allows for a transition from embedded to exposed piping without the need for additional elbow fittings. The design supports direct installation behind plasterboard or within wall cavities, making it suitable for both new builds and renovation projects. Its robust construction ensures long-term performance in environments with fluctuating temperatures and pressures.

Technical parameters

Installation and connection

Installation involves inserting the ALPEX pipe into the fitting and applying a press tool to secure the connection. The fitting has a 16 mm internal diameter and a 1/2 inch female thread for external connections. Ensure the pipe is cut cleanly and free from burrs before insertion. Verify the alignment of the press tool with the fitting to avoid misalignment and incomplete pressing. Common mistakes include insufficient pressing force or using a worn press tool, which can lead to weak or faulty connections.

Compatibility and accessories

This fitting is specifically designed for use with ALPEX pipes and requires a compatible press tool for installation. Additional components such as press tools, cutting tools, and pipe supports may be necessary for a complete installation. Ensure all accessories are from the same system to maintain compatibility and system integrity.

Technical background for designers

The fitting operates by compressing the stainless steel sleeve around the ALPEX pipe when pressed, creating a watertight seal. The nickel-plated brass body offers corrosion resistance and durability, while the EPDM seal provides flexibility and a secure fit. The design allows for easy integration into existing systems and supports long-term performance in fluctuating thermal and hydraulic conditions. The material selection ensures compatibility with both cold and hot water, as well as heating fluids, without degradation over time.

Service and operation

Regular visual inspections should be conducted to ensure the integrity of the connections and detect any signs of wear or leakage. Check for proper alignment and secure pressing during installation. No specific service intervals are required for this component under normal operating conditions. In case of suspected failure, the fitting should be replaced following standard procedures for press connections.
