PUSH grommet - female thread- 20x3/4 "F IVAR.PUSH-PF

Product detailed description

This push grommet is commonly used in residential and commercial buildings for connecting flexible ALPEX pipes to internal threaded connections. Installers and technicians working on heating, plumbing and sanitation systems can use this fitting to create secure, leak-free joints in water supply lines, underfloor heating circuits or domestic hot and cold water systems. The fitting is particularly useful in tight spaces or where crimping tools are not available.

The compact design allows for easy installation in confined areas such as wall cavities, under floors or behind panels. It ensures a reliable mechanical and hydraulic connection between the ALPEX pipe and the internal thread of the system component, such as valves, meters or manifolds. The fitting is suitable for both new installations and repairs in systems operating under moderate pressure and temperature conditions.

Technical parameters

Material	Brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
EAN	4013960355772
Weight	0.112 kg
Code	87320773

The nominal pressure rating of PN 10 indicates that the fitting is suitable for systems operating at pressures up to 10 bar at room temperature. The maximum operating temperature of +120 °C makes it suitable for domestic hot water applications and underfloor heating systems. These parameters are essential for correct sizing and selection based on the system's operating conditions and the type of media being transported.Installation and connection To install the push grommet, first ensure that the ALPEX pipe is cut cleanly and free of burrs. Insert the pipe fully into the grommet until it reaches the stop. The internal thread of the grommet should then be connected to the corresponding female thread of the system component. Use an appropriate wrench to tighten the connection, ensuring that the thread is fully engaged without over-tightening. Check that the pipe is inserted to the correct depth and that the sealing ring is undamaged. Common installation errors include insufficient insertion of the pipe, which can lead to leaks, or cross-threading during tightening, which can damage the fitting or the component being connected. Always verify the alignment of the threads before applying torque.

Compatibility and accessories

This push grommet is specifically designed for use with ALPEX flexible pipes. It is compatible with standard internal thread connections and should be used in conjunction with the appropriate pipe size. No additional tools are required for installation. Related products include other push fittings and crimping tools for ALPEX systems.

Technical background for designers

The push grommet operates by mechanically gripping the ALPEX pipe and sealing against the internal thread. The brass body provides good corrosion resistance and mechanical strength, while the stainless steel sleeve ensures durability and resistance to wear. The EPDM sealing ring provides a reliable hydraulic seal even under fluctuating temperatures and pressures. The integration of this fitting into the system depends on the overall design of the piping network, including the layout of components and the thermal expansion characteristics of the materials used. The service life of the fitting is influenced by the quality of the installation, the operating conditions and the compatibility of the materials used in the system.

Service and operation

During operation, regular visual inspections should be carried out to check for signs of leakage, corrosion or mechanical damage. If any issues are identified, the fitting should be replaced immediately. No scheduled maintenance is required beyond these visual checks.

Frequently asked questions

Can this push grommet be used with other types of flexible pipe?
No, it is specifically designed for ALPEX pipe. Using it with other pipe types may result in improper sealing and potential leaks.

Is it necessary to use a lubricant when tightening the connection?
No, lubricants are not required. Over-lubrication can prevent the sealing ring from forming a proper hydraulic seal and may lead to leaks.

Can this fitting be used in steam systems?
No, the operating temperature limit of +120 °C means it is not suitable for steam applications. Use fittings rated for higher temperatures in such systems.

Can the fitting be reused after disassembly?
No, the sealing ring may be damaged during removal. It is recommended to replace the fitting with a new one to ensure a secure connection.
