PRESS wall - end wall, 20 x 1/2" F, left

Product detailed description

Press end wall fittings are essential components in modern plumbing and heating systems using ALPEX pipes. They are commonly used in residential and commercial buildings for connecting pipe ends to fixed structures such as walls or panels. These fittings are part of press-fit systems that eliminate the need for soldering or welding, reducing installation time and complexity. Installers typically use them in hot and cold water supply systems, heating circuits and sanitation lines where a secure, leak-free connection is required. The nickel-plated surface provides corrosion resistance, while the EPDM sealing ring ensures long-term tightness.

The press end wall fitting is often installed in concealed spaces behind walls or under floors, where accessibility is limited. It is particularly useful when a pipe needs to be terminated against a rigid surface. The installation process involves inserting the prepared pipe into the fitting and applying a defined pressing force using a certified tool. This creates a mechanical connection that maintains integrity even under thermal expansion and contraction.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.183 kg
Code	513012
Brand	IVAR

The operating temperature limit of +120°C makes this fitting suitable for hot water applications. The nominal pressure rating PN 10 indicates that the fitting can withstand pressures of up to 10 bar under normal operating conditions. These parameters are critical when selecting the correct component for the intended system and must be considered during design to ensure compliance with local standards and regulations.

Installation and connection

This press end wall fitting connects to a 20 mm diameter ALPEX pipe on one side and features a 1/2 inch female thread on the other. Before installation, the pipe must be cut cleanly and deburred to ensure a smooth insertion. The press tool must be calibrated to apply the correct amount of force to compress the sleeve around the pipe wall. The installer should verify that the pipe is fully inserted into the fitting and that the tool has engaged properly. Common mistakes include using incorrect cutting tools, failing to clean the pipe end, or applying insufficient or excessive pressing force. These errors can result in leaks or premature failure of the connection.

Compatibility and accessories

This fitting is specifically designed for use with ALPEX pipes and must be used in conjunction with compatible press tools and sleeves. When installing, ensure that all components are from the same system to guarantee proper performance. Additional accessories such as press tools, pipe cutters and measuring instruments may be required to complete the installation. No alternative or related products are specified for this model.

Technical background for designers

This press end wall fitting operates by mechanically securing the pipe within the fitting using a stainless steel sleeve. The sleeve is compressed around the pipe wall when a certified press tool applies a defined force, creating a permanent and reliable joint. The nickel-plated CW617N brass body offers high strength and resistance to corrosion, making it suitable for both hot and cold water applications. The EPDM sealing ring provides a flexible yet durable seal that remains effective over a wide range of temperatures. The design allows for easy integration into existing pipe systems while maintaining structural integrity and flow efficiency. The service life of the fitting depends on the quality of the installation, the condition of the pipe and the operating environment.

Service and operation

Once installed, the fitting requires no regular maintenance. However, periodic visual inspections are recommended to check for signs of wear, corrosion or leakage. If a leak is detected, the affected section must be isolated and the fitting replaced. No specific service intervals are provided for this model. The integrity of the connection should be verified during commissioning and after any major system changes.

Frequently asked questions

Can this fitting be used with copper pipes?
No, this fitting is specifically designed for ALPEX pipes and cannot be used with copper or other types of piping materials.

What press tool is required for this fitting?
A certified press tool compatible with ALPEX press fittings must be used to ensure a correct and durable connection.

Is it possible to reuse the fitting after pressing?
No, once the press operation is performed, the fitting cannot be reused. A new fitting must be installed for any replacement or repair work.

What is the maximum allowable pressure for this fitting?
The fitting is rated for a nominal pressure of PN 10, which corresponds to a maximum operating pressure of 10 bar at standard conditions.
