Extension 42 x 42

Product detailed description

Press extensions like the IVAR IVC11.42 are commonly used in central heating systems, fire protection, and industrial piping where secure, leak-free connections are essential. Installers working in residential, commercial and industrial buildings use these fittings to extend or adapt pipe runs without the need for welding or threading. The IVC11.42 is suitable for closed systems operating under pressure, including heating, chilled water, and ventilation systems. It is also compatible with dry air and inert gas applications, making it a versatile component in a range of technical installations.

Correct selection and installation of press fittings are crucial for system integrity. The IVC11.42 is designed for use with carbon steel pipes and press tools compatible with M-type jaws. It ensures a reliable seal through an EPDM O-ring and is suitable for both high-pressure and low-temperature environments. The extension is not certified for potable water applications, so designers must ensure it is used in appropriate media.

Technical parameters

The operating temperature range from -20°C to +120°C makes this extension suitable for both heating and cooling systems. The maximum pressure rating of 16 bar ensures it can handle high-pressure environments. The material, carbon steel with zinc coating, provides corrosion resistance and mechanical strength. These parameters are essential for determining compatibility with system conditions and for correct sizing in design stages.

Installation and connection

The IVAR IVC11.42 is installed using standard press tools compatible with M-type jaws. The fitting connects to 42 mm nominal pipe diameter and requires the pipe to be cut cleanly and deburred before insertion. The press tool must be applied evenly to ensure the jaws fully compress the fitting and the O-ring is seated correctly. The installation should be checked for alignment and even compression to prevent leaks. Common mistakes include using incorrect tooling, failing to clean the pipe end, or pressing without verifying the fit. The indicator mark on the fitting must align with the 54 mm dimension to confirm a complete press.

Compatibility and accessories

The IVC11.42 is compatible with IVAR press fittings and systems using carbon steel piping. It requires standard press tools and EPDM O-rings for sealing. No additional accessories are required for standard installation. It is not compatible with copper or stainless steel pipe systems and should not be used in potable water applications. Related products include other IVAR press fittings and tools designed for M-type jaw systems.

Technical background for designers

The IVAR IVC11.42 operates on the press-fit principle, where mechanical jaws compress the fitting around the pipe to create a secure, leak-free joint. The zinc-coated carbon steel provides durability and resistance to corrosion in non-potable water and industrial media. The EPDM O-ring ensures a flexible and reliable seal across the operating temperature range. The fitting integrates into closed systems by maintaining pressure integrity and thermal stability. The service life and efficiency depend on correct installation, compatibility with system media, and the absence of mechanical stress or vibration in the installation environment.

Service and operation

The IVAR IVC11.42 requires no regular maintenance under normal operating conditions. However, it should be visually inspected for signs of mechanical damage, corrosion or leakage. If the fitting is suspected of being compromised, it should be replaced immediately. The system should be depressurised and isolated before any inspection or replacement. No specific service intervals are required, but routine checks during system maintenance are recommended.
