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

Product detailed description

End walls are essential components in press-fit pipe systems, particularly in residential and commercial heating and plumbing installations. They are used to terminate pipe runs in systems where a secure and leak-free connection is required. Installers working with ALPEX pipes will find this fitting suitable for applications involving hot water and heating circuits. The design allows for quick and reliable installation without the need for additional tools beyond the press equipment.

Correct selection and installation of end walls are crucial for the long-term performance of the system. The fitting must be compatible with the pipe material and system pressure. This model is intended for use in closed systems with moderate operating conditions, ensuring dimensional stability and resistance to corrosion.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.141 kg
Code	513002
Brand	IVAR

The nominal pressure rating of PN 10 indicates that the fitting is suitable for systems operating at up to 10 bar. The maximum operating temperature of +120°C makes it compatible with hot water and heating systems. The material selection ensures mechanical strength and resistance to chemical and thermal stress, which is essential for long-term performance in press-fit systems.

Installation and connection

The fitting connects to a 20 mm ALPEX pipe and features a female thread of 1/2 inch. The installation process involves inserting the pipe into the fitting and pressing it using a suitable press tool. It is important to ensure that the pipe is fully inserted and that the press tool is correctly aligned to avoid misalignment or incomplete pressing. Common installation errors include using incorrect press tools or failing to check the pipe insertion depth before pressing. After installation, the connection should be visually inspected for uniform pressing marks and correct alignment.

Compatibility and accessories

This end wall is specifically designed for use with ALPEX pipes and requires a press tool compatible with the fitting's dimensions. It is not intended for use with other pipe materials or connection methods. No additional accessories are required for installation, but it is important to ensure that the press tool is correctly calibrated and maintained to achieve a reliable connection.

Technical background for designers

The operating principle of this fitting relies on the mechanical deformation of the sleeve during pressing, which creates a tight and durable connection between the pipe and the fitting. The nickel-plated brass CW617N provides high mechanical strength and corrosion resistance, while the stainless steel sleeve ensures compatibility with the press tool and maintains the integrity of the connection. The EPDM sealing material is resistant to thermal expansion and contraction, ensuring a stable seal over time. The integration of this fitting into the system depends on the correct sizing and alignment of the pipe, as well as the use of compatible press tools.

Service and operation

This fitting requires no regular maintenance once installed correctly. However, it is important to inspect the connection periodically for signs of wear, leakage, or misalignment. If the system is subjected to abnormal operating conditions, such as excessive pressure or temperature fluctuations, the connection should be re-evaluated for integrity. No specific service intervals are required for this model.

Frequently asked questions

Can this end wall be used with other pipe materials besides ALPEX?
No, this fitting is specifically designed for use with ALPEX pipes and is not compatible with other pipe materials.

Is it possible to reuse the fitting after pressing?
No, once the fitting has been pressed, it cannot be reused. A new fitting must be installed for any replacement or repair.

What type of press tool is required for installation?
A press tool compatible with the fitting's dimensions and the ALPEX pipe system is required. The tool must be correctly calibrated to ensure a reliable connection.

Can the fitting be used in systems with higher operating temperatures?
No, the maximum operating temperature is specified as +120°C. Use in systems with higher temperatures is not recommended and may compromise the integrity of the connection.
