PRESS Wall - through, 18 x 1/2" F x 18, straight

Product detailed description

This press-through wall fitting is commonly used in residential and commercial buildings for connecting ALPEX pipes within wall structures. Installers working on central heating systems, hot water supply lines, or drainage networks will find this fitting suitable for applications requiring a direct connection through a wall barrier. The fitting allows for the passage of a pipe through a structural wall while maintaining a secure and sealed connection on both sides. This is particularly useful in multi-layered wall constructions where space is limited and accessibility is restricted after installation.

The fitting is designed for use with ALPEX pipes of the same nominal diameter and requires a compatible pressing tool for installation. It is typically used in conjunction with press sleeves and EPDM seals to ensure a leak-free connection. The nickel-plated brass construction provides corrosion resistance and durability under standard operating conditions.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.198 kg
Code	513006
Brand	IVAR

The operating temperature limit of +120°C means this fitting is suitable for hot water and heating applications but not for steam or high-temperature industrial processes. The nominal pressure rating of PN 10 indicates the fitting is appropriate for low- to medium-pressure systems such as domestic heating circuits and water distribution. The CW617N nickel-plated brass is selected for its strength and resistance to corrosion in typical wet environments.

Installation and connection

The fitting is installed using a standard press tool compatible with ALPEX systems. The pipe is inserted fully into the fitting until it reaches the stop mark. The pressing sleeve is then placed over the joint and pressed using the appropriate tool. The connection size is 18 mm on both ends, with a 1/2 inch female thread for one side. The installer must verify that the pipe is clean and free of burrs before pressing. Common mistakes include incomplete insertion of the pipe or incorrect pressing force, which can lead to leaks or weakened joints.

Compatibility and accessories

This fitting is specifically designed for use with ALPEX pipes of the same outer diameter. It requires a stainless steel pressing sleeve and an EPDM sealing ring for proper installation. Installers should also have access to a suitable pressing tool calibrated for ALPEX systems. Additional fittings such as press elbows or couplings may be needed depending on the layout of the installation.

Technical background for designers

The press-through wall fitting functions by securing the pipe within a metal sleeve and compressing a rubber seal around the joint. The nickel-plated brass body provides mechanical strength and thermal stability, while the EPDM sealing ensures a tight connection. The fitting is integrated into the system by aligning the pipe through the wall and pressing the sleeve to form a permanent joint. The service life of the fitting depends on the quality of the press, the condition of the pipe and the stability of the surrounding structure. Avoid using in vibrating or high-stress environments unless additional support is provided.

Service and operation

No regular maintenance is required for this fitting during normal operation. However, it should be visually inspected during routine system checks for signs of leakage, corrosion or mechanical damage. If a leak is detected, the fitting must be removed and replaced, as re-pressing is not recommended. The EPDM seal should be replaced if it shows signs of degradation due to prolonged exposure to heat or chemicals.

Frequently asked questions

Can this fitting be used for cold water supply?
Yes, the fitting is suitable for cold water applications as long as the operating pressure does not exceed PN 10 and the temperature remains below +120°C.

Is a specific pressing tool required for installation?
Yes, a standard ALPEX-compatible pressing tool is necessary to ensure the correct compression of the sleeve and secure joint formation.

Can the fitting be used vertically through a ceiling?
No, the fitting is designed for horizontal wall installations and should not be used in vertical or overhead positions where mechanical stress could affect the joint integrity.

Can the fitting be re-pressed if the initial installation fails?
No, the fitting is not designed for re-pressing. If the joint fails, the entire fitting must be removed and replaced with a new one.
