T-piece 90° - reduced - N - 18-15-18mm IVAR.IVN41

Product detailed description

This 90° reduced T-piece is commonly used in heating systems, fire protection installations, solar thermal circuits and industrial piping networks. It provides a reliable junction for connecting three pipes with different cross-sections via press-fit technology. The component is frequently found in residential, commercial and light industrial buildings, where space constraints require angular routing of pipelines. Installers working with stainless steel press systems will find this fitting essential for maintaining flow continuity while adapting to dimensional changes in the piping layout.

The fitting enables smooth transitions between 18 mm, 15 mm and 18 mm pipe diameters, making it useful when branching off smaller-diameter supply or return lines from larger-diameter mains. The press-fit method ensures fast and secure installation without the need for additional tools beyond a certified press unit. The EPDM sealing ring ensures tightness under nominal pressure conditions, provided correct installation and proper tool calibration are followed.

Technical parameters

Installation and connection

Before installation, verify that the pipe ends are clean, free from burrs and correctly sized to match the press-fit groove dimensions. Use a calibrated press tool compatible with IVAR press systems. Ensure the sealing ring is seated properly and the indicator mark aligns with the designated dimension (54 mm). Common errors include using non-certified tools, which can lead to incomplete compression or deformation of the fitting. Always double-check the alignment of the indicator mark after pressing to confirm a complete and uniform joint.

Compatibility and accessories

This T-piece is designed for use with IVAR stainless steel press pipes of corresponding diameters. For optimal performance, it should be paired with compatible press fittings and tools from the IVAR system. Accessories such as EPDM sealing rings must be sourced from the same system to maintain integrity and compliance with technical standards. When integrating into a larger system, ensure all adjacent components meet the same pressure and temperature requirements.

Technical background for designers

As a branch fitting, this T-piece allows directional change and diameter transition in a single component, reducing the need for multiple joints. The stainless steel body offers resistance to corrosion and scaling, making it ideal for aggressive media and long-term exposure to moisture. The EPDM seal ensures flexibility and resilience under varying thermal expansion rates. Longevity depends on correct installation practices, adherence to maximum operating parameters and avoiding mechanical stress at the joints.

Service and operation

No routine maintenance is required for this component unless leakage occurs due to improper installation. In such cases, disassemble the joint and inspect the sealing ring and pipe ends for damage. Reinstall using a new seal and certified pressing technique. There are no scheduled service intervals outlined for this fitting under normal operating conditions.

Frequently asked questions

Can this T-piece be used in solar thermal systems?
Yes, the temperature range includes +120 °C, which is suitable for solar thermal applications.

Is it possible to connect this T-piece to copper pipes?
No, it is designed exclusively for stainless steel press pipes and cannot be used with copper or other materials.

What happens if the indicator mark is not visible after pressing?
If the indicator does not reach the specified dimension, the joint is not fully compressed and may leak. The fitting must be reinstalled with a new seal.

Can this fitting be used in pneumatic systems?
Yes, it is suitable for compressed air applications within the stated temperature and pressure limits.
