Nipple PRESS - 26x26 IVAR.PT 5700

Product detailed description

Press couplings are essential components in modern heating and plumbing systems where reliable, leak-free connections are required. This type of fitting is commonly used in residential and commercial buildings for connecting plastic-steel composite pipes in central heating, hot and cold water distribution, and underfloor heating systems. Installers working with ALPEX pipe systems will encounter these fittings during pipe layout, system expansion or repair. The press coupling ensures a secure mechanical connection between two pipe ends, maintaining system integrity under operating pressure and temperature conditions.

Proper selection and installation of press couplings is critical to system performance. The coupling must match the pipe diameter and system requirements, including pressure and temperature parameters. The nickel-plated brass construction provides corrosion resistance and mechanical strength, while the EPDM sealing ring ensures a tight seal. The stainless steel sleeve supports the pipe during the pressing operation and contributes to long-term durability.

The operating temperature limit of +120 °C and PN 10 pressure rating define the system conditions for which this coupling is suitable. These parameters are essential for proper sizing and selection in accordance with the system design. The nickel-plated brass CW617N material is selected for its mechanical strength and resistance to corrosion in water-based systems. The EPDM sealing ring ensures compatibility with the internal media and maintains a tight seal under operating conditions.

Installation and connection

The coupling is installed using a press tool compatible with B-F-TH type jaws. The procedure involves positioning the coupling over the pipe ends and applying the press tool to compress the sleeve and secure the connection. The internal thread allows for connection to threaded components. It is important to ensure the pipe ends are clean and free from burrs before installation. Common installation errors include incorrect positioning of the coupling, insufficient pressing force, or using incompatible press tools, which can compromise the connection integrity.

Compatibility and accessories

This coupling is specifically designed for ALPEX plastic-steel composite pipes of equal diameter. It is compatible with other IVAR press fittings and components in the same system. For installation, a press tool with B-F-TH type jaws is required. Additional components such as pipe ends, press tools and sealing rings should be ordered according to the system requirements.

Technical background for designers

The press coupling operates by mechanically securing the pipe ends within the coupling body using a stainless steel sleeve. The sleeve is compressed during the pressing operation, creating a rigid connection. The nickel-plated brass CW617N material provides high mechanical strength and resistance to corrosion, ensuring long-term performance in water-based systems. The EPDM sealing ring is compatible with the internal media and maintains a tight seal under operating conditions. The coupling integrates into the system by providing a leak-free connection that maintains pressure and temperature integrity. The service life and efficiency depend on correct installation, system operating conditions and material compatibility.

Service and operation

Regular visual inspections are recommended to check for signs of wear, corrosion or leakage. The coupling does not require routine maintenance, but any damage to the sleeve or sealing ring should be addressed immediately. The system should be depressurised and drained before any inspection or repair work. No specific service intervals are defined for this component, but it should be replaced if any defects are detected during inspection.

Frequently asked questions

Can the coupling be used with other pipe types besides ALPEX?
No, the coupling is specifically designed for ALPEX plastic-steel composite pipes and is not suitable for other pipe types.

Is the coupling suitable for hot water systems?
Yes, the operating temperature limit of +120 °C makes it suitable for hot water systems as well as heating applications.

Can the coupling be used in systems with higher pressure than PN 10?
No, the pressure rating is defined as PN 10 and the coupling is not designed for higher pressure conditions.

What press tool is required for installation?
A press tool compatible with B-F-TH type jaws is required for proper installation of the coupling.
