PRESS wall - end - 1/2 "Fx20 IVAR.MP 5760

Product detailed description

The press wall end fitting is commonly used in gas distribution networks, particularly in buildings requiring safe and reliable connections for natural gas, biogas or liquefied petroleum gas (LPG) supply. Installers typically encounter these fittings in underground or indoor gas piping systems where long-term integrity and leak-free performance are essential. The fitting is suitable for both new installations and system repairs, especially when working with pre-insulated ALPEX pipes.

Its design allows for secure, compact installation with minimal space requirements. The fitting ensures a robust connection between pipe and wall, and is intended for use with press tools calibrated for the specific pipe and fitting dimensions. It is not suitable for high-temperature steam or chemical environments outside its specified parameters.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Code	513002MP
Brand	IVAR

The operating temperature range of +120°C and PN 10 pressure rating make this fitting suitable for medium-pressure gas systems. These values are important for determining correct sizing and compatibility with existing pipelines. The material choice also influences resistance to corrosion and mechanical stress during installation and operation.

Installation and connection

Before installation, verify that the pipe is clean and free from burrs or deformations. The fitting must be pressed onto the prepared end of the 22 mm ALPEX pipe using a compatible press tool. Ensure that the tool is correctly aligned and applied evenly to avoid misalignment or incomplete sealing. Check the O-ring for damage prior to pressing and confirm that the tool is set to the correct depth to ensure full contact between the pipe and fitting. Common errors include incorrect pressing force or using a tool not suited for the specific pipe size or material.

Compatibility and accessories

This press wall end is specifically designed for use with ALPEX insulated copper-PE composite pipes. To complete the installation, additional components such as straight press fittings, elbows or valves may be required depending on the layout. Accessories should be selected based on the same pressure and temperature specifications to maintain system integrity.

Technical background for designers

The nickel-plated brass CW617N body provides good strength and resistance to atmospheric corrosion, making it suitable for both indoor and outdoor environments. The internal seal is provided by an HNBR O-ring, which maintains flexibility and sealing effectiveness over a wide temperature range. The press connection eliminates the need for soldering or welding, reducing installation time and potential for thermal damage to surrounding structures. System longevity is affected by correct installation practices, environmental exposure and adherence to recommended operating conditions.

Service and operation

Periodic visual inspections are recommended to check for signs of mechanical damage, corrosion or leakage. Since this fitting does not require regular servicing beyond initial installation, maintenance is generally limited to replacing damaged components. Any suspected leaks should be investigated using appropriate leak detection methods, such as soap solution testing, and faulty fittings should be replaced immediately.

Frequently asked questions

Can the press wall end be used with other pipe materials besides ALPEX?
No, it is specifically designed for ALPEX insulated copper-PE composite pipes and cannot be used with alternative materials without compromising the seal.

Is it possible to re-use the fitting after pressing?
No, once the press connection is made, the fitting cannot be removed or reused without damaging the seal or pipe integrity.

What is the minimum bend radius for this elbow in a gas line?
There is no bend radius requirement since this is a fixed 90° elbow. The fitting is designed for direct installation without bending.

How can I confirm that the press was successful?
After pressing, inspect the fitting for even tool marks and ensure the tool depth indicator shows full engagement. A successful press will also show no visible gaps between the pipe and fitting.
