Nipple PRESS - 32x32 IVAR.PT 5700

Product detailed description

Press fittings are essential components in modern heating and plumbing systems, particularly where plastic-copper composite piping is used. The IVAR 510020 press nipple is commonly installed in residential and commercial buildings to connect straight sections of ALPEX pipe. It is used in systems where a secure, leak-free connection is required without the need for soldering or threading. Installers typically work with this component in underfloor heating, domestic hot water, and central heating applications where the system operates within defined thermal and pressure limits.

Proper installation requires attention to alignment, tool calibration, and the correct use of press tools. The fitting is designed to be used with press tools compatible with B-F-TH jaw types, ensuring a consistent and reliable connection. The fitting is not suitable for dynamic or high-vibration environments unless additional mechanical support is provided.

The operating temperature limit of +120°C and nominal pressure of PN 10 are critical for system design. These values determine the suitability of the fitting for hot water or heating circuits. The material selection of nickel-plated brass CW617N ensures resistance to corrosion and mechanical wear, making it appropriate for long-term use in closed-loop systems.

Installation and connection

The IVAR 510020 press nipple is connected to ALPEX pipes of the same diameter using a press tool. The fitting has an internal thread for connecting to other threaded components. Before installation, ensure the pipe is clean and free of burrs. The press tool must be calibrated to the correct pressure and jaw type (B-F-TH) to ensure a full and even press. A common mistake is using an incorrect jaw type or insufficient press force, which can lead to leaks or weak connections. After pressing, the connection should be visually inspected for deformation or misalignment.

Compatibility and accessories

This press nipple is specifically designed for use with ALPEX plastic-copper composite pipes. It is compatible with other IVAR press fittings and tools. For complete system integration, installers may need to order additional components such as press couplings, elbows, or valves. No specific accessories are required for installation, but a suitable press tool with B-F-TH jaws is essential.

Technical background for designers

The press fitting operates by compressing a stainless steel sleeve around the pipe and fitting, creating a mechanical and hydraulic seal. The nickel-plated brass body provides a durable and corrosion-resistant surface, while the EPDM sealing material ensures a tight fit. The CW617N brass alloy is selected for its strength and compatibility with copper and plastic materials. The fitting integrates into the system without the need for additional supports in most static applications. Long-term performance depends on correct installation, system pressure, and temperature conditions.

Service and operation

No regular maintenance is required for the IVAR 510020 press fitting under normal operating conditions. However, periodic visual inspections are recommended to check for signs of mechanical stress, corrosion, or leakage. If a connection fails, it must be cut out and replaced with a new fitting. There are no defined service intervals for this component as it is a one-time installation item.

Frequently asked questions

Can the IVAR 510020 be used with copper-only pipes?
No, this fitting is specifically designed for ALPEX plastic-copper composite pipes. Using it with copper-only pipes may result in improper sealing or mechanical failure.

Is the internal thread compatible with standard plumbing components?
Yes, the internal thread is standard and can be connected to other threaded components such as valves or meters, provided the thread type and size match.

Can this fitting be used in high-pressure systems?
No, the nominal pressure limit is PN 10. Exceeding this pressure may cause failure of the connection or the fitting itself.

Is it possible to reuse the fitting after pressing?
No, once the fitting has been pressed, it cannot be reused. A new fitting must be installed if the connection needs to be replaced or modified.
