PRESS Wall - through, 16 x 1/2" F x 16, straight

Product detailed description

This press wall fitting is commonly used in residential and commercial heating and plumbing systems where ALPEX pipes are installed. It provides a secure and leak-free connection between the pipe and the wall, ensuring long-term reliability in both new builds and renovation projects. Installers typically work with this component in underfloor heating systems, domestic hot and cold water lines, and other applications where compact and durable fittings are required. The fitting is designed for use in environments where the system operates within the specified temperature and pressure limits.

When installing, the fitting is pressed using a certified press tool to create a permanent mechanical bond between the pipe and the fitting. The connection is suitable for both horizontal and vertical installations and is often integrated into manifold systems or wall-mounted pipe layouts. It is essential to ensure that the ALPEX pipe is correctly cut and free from burrs before pressing to avoid compromising the integrity of the seal.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.182 kg
Code	513005
Brand	IVAR

The operating temperature of +120°C makes this fitting suitable for hot water and heating applications. The PN 10 pressure rating indicates that it can handle nominal pressures of 10 bar, which is typical for most residential and light commercial systems. These parameters are critical for ensuring the fitting is correctly sized and selected for the intended application, particularly in systems with higher thermal loads or pressure fluctuations.

Installation and connection

The fitting is installed by inserting the prepared ALPEX pipe into the fitting and pressing it using a calibrated press tool. The connection size is 16 x 1/2 inch F x 16, meaning it connects two 16 mm ALPEX pipes with a 1/2 inch female thread on the wall side. It is important to verify that the pipe is fully seated before pressing and that the tool is set to the correct depth to avoid under- or over-pressing. Common installation mistakes include using incorrect tools, failing to clean the pipe ends, or attempting to reuse a fitting after pressing, which can lead to leaks or system failure.

Compatibility and accessories

This press wall fitting is specifically designed for use with ALPEX pipes of the same diameter. It requires a compatible press tool for installation and should be used in conjunction with other IVAR press fittings and components to maintain system integrity. No additional accessories are required for standard installation, but it is recommended to have spare seals and sleeves on hand for replacements or repairs.

Technical background for designers

The fitting operates by forming a mechanical and hydraulic seal between the press sleeve and the pipe wall when pressed. The nickel-plated brass body provides corrosion resistance and durability, while the stainless steel sleeve ensures long-term stability under pressure. The EPDM sealing material is compatible with water and glycol-based media and maintains flexibility across the operating temperature range. The integration of this fitting into the system depends on correct alignment and press depth, which directly affects the service life and efficiency of the connection.

Service and operation

Once installed, the fitting requires no regular maintenance and is designed for a long service life. However, it is important to inspect the connection visually for signs of stress, corrosion, or leakage during routine system checks. If a leak is detected, the fitting must be replaced as it cannot be repaired or re-pressed. No specific service intervals are required for this component under normal operating conditions.

Frequently asked questions

Can this fitting be used with other pipe materials besides ALPEX?
No, it is specifically designed for ALPEX pipes and cannot be used with copper, steel or other plastic pipe types.

Is it possible to re-press the fitting after the initial pressing?
No, the fitting is designed for one-time pressing only. Re-pressing may compromise the integrity of the connection.

Can the fitting be used in systems with higher than 120°C operating temperatures?
No, the maximum operating temperature is specified as +120°C. Exceeding this may cause material degradation and failure.

What is the recommended press depth for this fitting?
The press depth must be set according to the manufacturer's specifications for the fitting model and pipe diameter. This information is provided in the tool's calibration guide.
