PRESS wall - through, 18 x 1/2" F

Product detailed description

Press wall-through fittings are essential components in modern heating and plumbing systems where pipes need to pass through walls or partitions. These fittings are commonly used in residential and commercial buildings for underfloor heating, domestic hot water distribution, and central heating systems. Installers working with ALPEX pipes will find these fittings ideal for ensuring leak-free connections in concealed installations. The press connection method eliminates the need for soldering or threading, reducing installation time and ensuring consistent quality.

Wall-through fittings are typically installed during the construction phase or during system retrofitting. They allow for the secure passage of pipes through structural elements while maintaining the integrity of the system. The installation requires careful alignment and pressing to ensure a tight seal. These fittings are particularly useful in applications where space is limited and accessibility is restricted after installation.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.392 kg
Code	510063
Brand	IVAR

The nominal pressure rating of PN 10 indicates the fitting is suitable for low-pressure systems, such as heating and domestic water supply. The maximum operating temperature of +120°C makes it compatible with hot water circuits and underfloor heating systems. These parameters are critical for ensuring the fitting can withstand the thermal and hydraulic conditions of the system without failure.

Installation and connection

The fitting has a 18 mm ALPEX pipe connection on one side and a 1/2 inch female thread on the other. The press connection requires a dedicated pressing tool to compress the stainless steel sleeve around the pipe, creating a watertight seal. Installers should verify that the pipe is correctly inserted into the fitting and that the pressing tool is properly aligned with the pressing zone. Common installation errors include misalignment of the tool, insufficient pressing force, or using the wrong tool for the fitting size. After pressing, the connection should be visually inspected for even compression and absence of gaps.

Compatibility and accessories

This fitting is specifically designed for use with ALPEX pipes of the same diameter. It is compatible with press tools of type B-F-TH. For complete system integration, additional components such as press elbows, couplings, and valves may be required. Installers should ensure that all components are from the same manufacturer or are certified for use with ALPEX systems to maintain system integrity.

Technical background for designers

The press connection operates by compressing a stainless steel sleeve around the pipe, creating a mechanical and hydraulic seal. The nickel-plated brass body provides corrosion resistance and durability in wet environments. The EPDM sealing material ensures flexibility and long-term sealing performance. When designing systems, it is important to consider the thermal expansion of the pipe and the structural movement of the building to prevent stress on the fitting. The material properties of the fitting ensure compatibility with both hot and cold water, making it suitable for a wide range of applications.

Service and operation

No regular maintenance is required for this fitting under normal operating conditions. However, periodic visual inspections are recommended to check for signs of corrosion, leakage, or mechanical damage. If the fitting is exposed to temperatures exceeding +120°C or pressures beyond PN 10, it should be replaced immediately to prevent system failure. There are no scheduled service intervals specified for this component.

Frequently asked questions

Can this fitting be used with copper pipes?
No, this fitting is specifically designed for ALPEX pipes and is not compatible with copper or other pipe materials.

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

Can this fitting be used in steam systems?
No, the maximum operating temperature of +120°C makes it unsuitable for steam applications, which typically exceed this limit.

Can the fitting be used in chilled water systems?
Yes, the fitting is suitable for both hot and cold water systems, provided the operating pressure and temperature remain within the specified limits.
