Press gland - external thread, 5/4" M x 32

Product detailed description

Press fittings are essential components in modern heating and plumbing systems, particularly where ALPEX piping is used. This type of fitting is commonly found in residential and commercial buildings, including underfloor heating systems, domestic hot and cold water supply, and central heating circuits. Installers and technicians working with these systems will frequently encounter the need to connect flexible ALPEX piping to rigid threaded components such as valves, radiators, or pipe fittings. The press fitting provides a secure, leak-free connection without the need for soldering or threading, reducing installation time and complexity.

Proper selection and installation of press fittings are critical to system performance and longevity. The fitting must match the pipe size, thread type, and system pressure and temperature requirements. This particular model is designed for use in systems operating at up to 120°C and with a nominal pressure of PN 10. It is suitable for connecting ALPEX pipe to an internal thread, ensuring compatibility with standard threaded components in the system.

Technical parameters

Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.285 kg
Code	510106
Brand	IVAR

The nominal pressure of PN 10 indicates that the fitting is suitable for systems with a maximum working pressure of 10 bar. The operating temperature of +120°C makes it appropriate for use in hot water systems and heating applications. The material combination of nickel-plated brass and EPDM sealing ensures resistance to corrosion and chemical media typically found in plumbing and heating systems. These parameters are essential for correct sizing and selection, ensuring the fitting meets the system's hydraulic and thermal demands.

Installation and connection

To install the press fitting, the ALPEX pipe is first cut to the correct length using a suitable pipe cutter. The pipe is then inserted into the fitting until it reaches the stop mark. A press tool compatible with the fitting type (B-F-TH) is used to apply the required pressure, forming a secure connection. The external thread of 5/4 M x 32 must be checked for cleanliness and damage before installation. Common installation mistakes include incorrect press force, misalignment of the pipe and fitting, and failure to verify the thread compatibility with the mating component. After installation, the connection should be visually inspected for proper press marks and leaks under pressure.

Compatibility and accessories

This press fitting is specifically designed for use with ALPEX pipe and is compatible with standard internal thread components. It requires a press tool of type B-F-TH for installation. No additional sealing materials are required, as the EPDM sealing is integrated into the fitting. Installers should ensure that the mating threaded component has the correct internal thread size and is free from damage or debris. No related products are available for this model.

Technical background for designers

The press fitting operates by mechanically deforming the fitting around the pipe, creating a tight, leak-free seal. The nickel-plated brass CW617N material provides good mechanical strength and corrosion resistance, while the stainless steel sleeve ensures durability during the pressing process. The EPDM sealing is resistant to water and common chemicals found in heating and plumbing systems. The fitting integrates into the system by providing a reliable connection between flexible ALPEX pipe and rigid threaded components. The service life and efficiency of the fitting are influenced by correct installation, adherence to pressure and temperature limits, and the quality of the mating components.

Service and operation

No regular maintenance is required for this press fitting during normal operation. However, it should be inspected periodically for signs of wear, corrosion, or leakage. If a leak is detected, the fitting should be replaced immediately. There are no specified service intervals for this model, as it is designed for long-term use under the stated operating conditions. The fitting should not be subjected to mechanical stress or excessive pressure beyond its rated limits.

Frequently asked questions

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

Is it possible to reuse the fitting after pressing?
No, once the fitting has been pressed, it cannot be reused and must be replaced if the connection needs to be changed or repaired.

What press tool is required for installation?
A press tool of type B-F-TH is required for this fitting to ensure a proper and secure connection.

Can this fitting be used in systems with higher pressure than PN 10?
No, the fitting is rated for a maximum nominal pressure of PN 10 and should not be used in systems exceeding this limit.
