Elbow PUSH 90°- PPSU - 26x26 IVAR.PUSH-K

Product detailed description

This 90° push elbow is commonly used in residential and commercial heating and plumbing systems where quick and reliable pipe connections are required. It is ideal for applications involving ALPEX pipes, where the installer needs to create a right-angle turn without the use of crimping tools. The fitting is suitable for systems operating at a nominal pressure of PN 10 and a maximum temperature of +120°C. It is typically installed in underfloor heating, domestic hot water, and general plumbing systems where flexibility and ease of installation are key.

As a PPSU-based fitting, it offers good resistance to thermal and mechanical stress, making it suitable for long-term use in environments with fluctuating temperatures. The push connection ensures a secure and leak-free joint, reducing the risk of installation errors and the need for additional tools. The EPDM sealing ring and stainless steel sleeve contribute to the durability and reliability of the connection.

Technical parameters

Installation and connection

To install the 90° push elbow, first ensure that the ends of the ALPEX pipes are clean and free from burrs. Insert each pipe into the respective end of the fitting until it reaches the stop. The push connection is designed for a secure fit without the need for crimping or additional tools. Verify that the pipe is fully seated and that the EPDM sealing ring is not damaged during installation. Common mistakes include insufficient insertion depth or using the fitting with incompatible pipe diameters. Always confirm that the pipe diameter matches the 26 x 26 dimensions of the fitting.

Compatibility and accessories

This 90° push elbow is specifically designed for use with ALPEX pipes of the same diameter. It is compatible with other PPSU push fittings from IVAR, including straight couplings and other elbow types. When installing, ensure that all components are from the same system to maintain compatibility and system integrity. No additional tools are required for installation, but it is recommended to have a set of standard plumbing tools on hand for pipe preparation and inspection.

Technical background for designers

The push connection operates on the principle of a mechanical lock and seal provided by the EPDM sealing ring and the stainless steel sleeve. The PPSU material is chosen for its high thermal resistance and dimensional stability, making it suitable for use in systems with fluctuating temperatures. The fitting integrates into the system by providing a rigid connection point that supports the structural integrity of the piping layout. The service life and efficiency of the fitting depend on proper installation, correct system pressure and temperature conditions, and the absence of mechanical stress from pipe movement or external forces.

Service and operation

During operation, the fitting requires no active maintenance. However, periodic visual inspections are recommended to check for signs of wear, deformation, or leakage. Ensure that the system pressure and temperature remain within the specified limits. If the fitting is subjected to excessive mechanical stress or thermal cycling, it may degrade over time. There are no defined service intervals for this component, as it is designed for long-term use under normal operating conditions.

Frequently asked questions

Can this fitting be used with other types of plastic pipes?
No, this fitting is specifically designed for ALPEX pipes. Using it with other pipe types may result in a poor connection or system failure.

Is it possible to reuse the fitting after disassembly?
No, the EPDM sealing ring may be damaged during disassembly, and the fitting is not intended for reuse. A new fitting should be installed for each connection.

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

What tools are required for installation?
No special tools are required for installation. A standard set of plumbing tools for pipe cutting and deburring is sufficient.
