Press gland - external thread, 2" 1/2 M x 75

Product detailed description

This press fitting is commonly used in central heating, plumbing, and sanitation systems to connect ALPEX pipes to threaded components such as valves, meters, or manifolds. The fitting is ideal for applications involving hot water distribution, underfloor heating, or domestic hot water circuits. Installers working on residential or commercial buildings will benefit from the secure, leak-free connection provided by the press technology. The fitting is designed for use in systems where a reliable and durable connection is required under normal operating conditions.

The installation is typically carried out in mechanical rooms, under floors, or within wall cavities where access is limited. The fitting allows for quick and accurate connections without the need for soldering or threading, reducing installation time and potential for human error. The nickel-plated brass body ensures corrosion resistance and long-term stability in wet environments.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
EAN	4013960370867
Weight	1.15 kg
Code	86775769
Brand	IVAR

The nominal pressure rating of PN 10 indicates the fitting is suitable for systems with a maximum allowable pressure of 10 bar at standard temperatures. The operating temperature limit of +120°C makes it appropriate for hot water circuits but not for steam or high-temperature industrial applications. These parameters are essential for ensuring correct sizing and selection based on the system’s design load and thermal conditions.

Installation and connection

To install, ensure the ALPEX pipe is cut cleanly and free of burrs. Insert the pipe into the fitting until it reaches the stop mark. Use pliers of type B-F-TH to apply even pressure around the circumference of the fitting. After pressing, verify the connection with a go/no-go gauge if available. A common mistake during installation is using incorrect or worn pliers, which can lead to incomplete pressing and compromised integrity. Always inspect the pipe for kinks or damage before pressing.

Compatibility and accessories

This fitting is specifically designed for ALPEX piping systems and requires compatible pliers for pressing. It should be used with standard internal-threaded components such as valves or adapters. No additional sealing compounds are needed due to the EPDM seal integrated into the fitting. Ensure all components in the system are rated for the same operating conditions to maintain overall system integrity.

Technical background for designers

Press fittings rely on a mechanical deformation of the fitting’s sleeve to create a tight seal around the pipe. The nickel-plated brass body resists corrosion and wear, while the stainless steel sleeve ensures a strong grip on the pipe. The EPDM seal provides flexibility and resilience against thermal expansion and contraction. The fitting is integrated into the system by aligning the pipe with the internal thread and securing it through the pressing process. Longevity is influenced by the quality of the pressing, the condition of the pliers, and the system’s operating parameters.

Service and operation

No regular maintenance is required for this fitting once correctly installed. However, it is important to periodically inspect the connection for signs of leakage or mechanical stress, especially in areas with high vibration or thermal cycling. In case of failure, the entire fitting must be replaced rather than repaired, as the press connection cannot be undone.

Frequently asked questions

Can this fitting be used with copper pipes?
No, this fitting is specifically designed for ALPEX pipes and will not provide a secure connection with copper.

Is it possible to reuse a pressed fitting?
No, once the fitting has been pressed, it cannot be reused. A new fitting must be installed in case of replacement or repair.

What type of pliers are required for pressing?
Only pliers of type B-F-TH are suitable for this fitting. Using other types may result in an incomplete or failed connection.

Can the fitting be used in steam systems?
No, the maximum operating temperature of +120°C limits its use to hot water systems, not steam or high-temperature applications.
