Press gland - internal thread, 1/2" F x 18

Product detailed description

This press fitting is commonly used in residential and commercial buildings for connecting flexible ALPEX piping to rigid threaded components. It is frequently found in central heating systems, underfloor heating circuits and hot and cold water distribution networks. Installers working with these systems often require reliable transitions between flexible and rigid piping. The fitting ensures a secure mechanical and hydraulic connection without the need for soldering or threading tools.

The fitting is suitable for applications involving domestic hot water, heating circuits and general plumbing. Its nickel-plated brass body provides resistance to corrosion and wear, while the EPDM sealing ring ensures a watertight connection. The stainless steel sleeve enhances durability and ensures even pressure distribution during pressing. It is essential to verify the compatibility with the pressing tool and the correct dimensions of the ALPEX pipe before installation.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.074 kg
Code	510045
Brand	IVAR

These parameters define the operational limits and material properties of the fitting. The maximum operating temperature of +120 °C makes it suitable for hot water applications. The nominal pressure rating of PN 10 ensures safe operation in standard heating and plumbing systems. The material composition ensures long-term reliability in aggressive environments.Installation and connection To install the fitting, the ALPEX pipe must be cut cleanly and stripped of insulation and inner protective layer according to the manufacturer’s specifications. The fitting is then slid over the pipe and positioned correctly. A pressing tool compatible with the B-F-TH jaw type is used to apply the required force to the sleeve, ensuring a secure joint. The internal thread allows for connection to standard threaded components such as valves, radiators or manifolds. Key checks include verifying the correct depth of the fitting on the pipe, ensuring the sleeve is fully compressed and confirming that the thread is clean and undamaged. Common installation errors include using incorrect pressing tools, insufficient stripping of the pipe insulation, or applying excessive force during pressing which can damage the fitting or pipe.Compatibility and accessories This press fitting is specifically designed for use with ALPEX pipes. It requires a pressing tool with jaws of the B-F-TH type to complete the installation. The internal thread allows for direct connection to standard threaded components without additional adapters. It is important to ensure that the ALPEX pipe is correctly prepared before installation. No additional sealing compounds or tapes are required due to the EPDM sealing ring included in the design.

Technical background for designers

This fitting operates by compressing the stainless steel sleeve around the ALPEX pipe during pressing, creating a mechanical and hydraulic seal. The nickel-plated brass body provides high resistance to corrosion and thermal expansion, making it suitable for both hot and cold water applications. The EPDM sealing ring ensures a watertight connection and maintains integrity under varying temperatures and pressures. The nominal pressure rating of PN 10 allows for integration into standard domestic and commercial heating and plumbing systems. The design ensures minimal flow resistance and long-term stability within the system.Service and operation No regular maintenance is required for this fitting under normal operating conditions. However, periodic inspections should be carried out to check for signs of mechanical stress, leaks or corrosion. If the fitting is exposed to temperatures exceeding the specified limit or subjected to excessive mechanical strain, it may require replacement. There are no defined service intervals for this component as it does not contain moving parts and is designed for long-term use.

Frequently asked questions

Can this fitting be used with copper pipes?
No, this fitting is specifically designed for use with ALPEX pipes. Using it with copper pipes would require a different type of connection method.

Is it necessary to use sealing tape on the internal thread?
No, the EPDM sealing ring included in the fitting provides sufficient sealing. Additional sealing materials are not required.

Can the fitting be used in steam systems?
No, the maximum operating temperature of 120 °C limits its use to hot water applications. Steam systems typically exceed this temperature range.

How is the fitting secured during pressing?
The stainless steel sleeve is compressed around the ALPEX pipe using a pressing tool with jaws of the B-F-TH type. This ensures a secure and leak-free connection.
