PUSH grommet - female thread- 26x1 "F IVAR.PUSH-PF

Product detailed description

Push grommets are essential in hydronic systems where quick and reliable connections are required between flexible plastic piping and rigid threaded components. This type of fitting is commonly used in residential and commercial heating, plumbing, and sanitation systems. Installers working with ALPEX piping benefit from the tool-free installation process, which reduces time and complexity during system assembly. These fittings are particularly useful in tight spaces or where frequent disassembly is not required. The PN10 pressure rating ensures compatibility with standard domestic and light commercial applications.

Correct selection of push grommets is critical to system integrity. The dimensions and material properties must align with the piping system's operating conditions, including temperature and pressure. The internal thread allows for direct connection to standard threaded components such as valves, meters, or radiators. The EPDM sealing material ensures a watertight connection, while the brass body provides corrosion resistance and mechanical strength.

The operating temperature of +120°C and nominal pressure of PN10 define the conditions under which this fitting can be safely used. The material selection, particularly the CW617N brass body and EPDM seal, ensures compatibility with hot water and heating fluids. These parameters are essential for sizing and verifying that the fitting meets the system's hydraulic and thermal requirements.

Installation and connection

To install the push grommet, first ensure the ALPEX pipe is cut cleanly and free from burrs. Insert the pipe into the grommet until it reaches the stop mark. The internal thread of the grommet is designed for 1 inch internal thread connections. Apply a small amount of lubricant to the thread if needed, but avoid over-tightening to prevent damage to the sealing mechanism. Check that the pipe is fully seated and that the connection is secure. Common installation errors include using incorrect pipe diameters or failing to ensure a clean cut, which can compromise the seal and lead to leaks.

Compatibility and accessories

This push grommet is specifically designed for ALPEX piping with an outer diameter of 26 mm. It is compatible with standard 1 inch internal thread fittings. No additional tools are required for installation, but a suitable cutting tool and deburring tool are recommended for preparing the pipe. No related products are listed for this model.

Technical background for designers

The push grommet operates by mechanically gripping the outer surface of the ALPEX pipe and sealing against it using an EPDM ring. The CW617N brass body offers good thermal and mechanical stability, making it suitable for long-term use in heating and hot water systems. The PN10 rating ensures the fitting can handle the typical pressures found in domestic and light commercial applications. The system's efficiency and service life depend on correct installation, proper pipe preparation, and adherence to the operating temperature and pressure limits.

Service and operation

No specific service intervals are provided for this fitting. During operation, it is important to periodically inspect the connection for signs of leakage or mechanical stress. If a leak is detected, the fitting should be replaced rather than repaired, as the sealing mechanism is not designed for re-use. Ensure that the system does not exceed the maximum operating temperature or pressure to avoid premature failure.

Frequently asked questions

Can this grommet be used with copper pipe?
No, this grommet is specifically designed for ALPEX piping and is not suitable for copper or other rigid metal piping.

Is this fitting suitable for high-pressure systems?
No, the nominal pressure rating is PN10, which is appropriate for standard domestic and light commercial applications only.

Can the grommet be reused after disassembly?
No, the sealing mechanism is not designed for re-use. A new grommet should be installed if the connection is disassembled.

What tools are required for installation?
Only a pipe cutter and deburring tool are required for preparing the ALPEX pipe. No additional tools are needed for fitting installation.
