Extension 35 x 35

Product detailed description

This press extension is commonly used in closed heating systems, fire sprinkler systems, and industrial air or gas ducting. It is suitable for environments where mechanical strength and resistance to high pressure are required. Installers working on central heating, refrigeration, or solar systems will find this component ideal for connecting press-fitted piping without the need for welding or threading. The EPDM seal ensures a leak-proof connection under normal operating conditions.

Designed for use in pressurised systems, this extension is frequently installed in residential, commercial, and industrial buildings. It is particularly useful in applications involving dry air, inert gases, or permanently water-filled systems. The extension is lightweight and compatible with a wide range of press tools, making it a versatile choice for installers working on complex piping layouts.

The extension is rated for a nominal pressure of 16 bar and can withstand high-pressure conditions up to that limit. It is suitable for operation in environments with temperatures as low as -20°C and up to a maximum of +120°C. These parameters are essential for ensuring correct sizing and compatibility with the system’s operating conditions and media type.Installation and connection The IVC11.35 press extension is installed using a press tool compatible with Type M jaws. The connection is made by inserting the pipe into the fitting and applying pressure until the crimp indicator is engaged. The fitting has a 35 mm diameter on both ends, and the press tool must be correctly aligned to avoid misalignment or incomplete crimping. Installers should verify that the O-ring is seated properly and that the crimp indicator is fully engaged. Common mistakes include using incorrect jaw types or insufficient pressure, which can lead to leaks or system failure.Compatibility and accessories This extension is compatible with other IVAR press fittings and pipes of the same diameter. It is intended for use with carbon galvanized steel piping and requires a press tool with Type M jaws for installation. No additional sealing compounds or coatings are required, as the EPDM O-ring provides a sufficient seal. Installers should ensure that all components are from the same system to maintain compatibility and system integrity.Technical background for designers The extension operates by forming a mechanical and hydraulic seal through the press tool, which compresses the fitting around the pipe. The carbon galvanized steel provides good resistance to corrosion and mechanical damage, while the EPDM O-ring ensures a tight seal under operating conditions. The fitting is designed for integration into pressurised systems and is suitable for use with water, dry air, and inert gases. The service life and efficiency of the fitting depend on correct installation, system pressure, and environmental conditions such as temperature and exposure to chemicals.Service and operation No regular maintenance is required for this fitting under normal operating conditions. However, installers should periodically inspect the system for signs of leaks or mechanical damage. The EPDM O-ring should remain intact and free from deformation or wear. If the crimp indicator is damaged or the fitting shows signs of stress, the component should be replaced to prevent system failure.Frequently asked questions

Can the IVC11.35 be used in fire protection systems?
Yes, the extension is suitable for fire protection ducting as it is rated for high pressure and can operate in water-filled systems.

Is the extension compatible with other IVAR press fittings?
Yes, it is designed to work with other IVAR press fittings and pipes of the same diameter when installed with the correct tooling.

Can the fitting be used in solar systems?
Yes, it is suitable for installation in solar ducting systems, provided the operating temperature does not exceed +120°C.

Does the extension require additional sealing compounds?
No, the EPDM O-ring provides a sufficient seal, and no additional compounds are needed for installation.
