T-piece 108 x 76.1 x 108

Product detailed description

Reduced T-pieces are essential components in closed pressurised systems for central heating, fire suppression, refrigeration and industrial air or gas transport. Installers working on residential, commercial or industrial buildings often use these fittings to create branch connections in ductwork. The T-piece allows for the integration of secondary circuits or components without the need for welding or threaded joints. It is particularly suitable for systems where high pressure resistance and a wide operating temperature range are required, such as in central heating systems, fire water supply lines or industrial air conditioning ducts.

These fittings are commonly used in closed-loop systems where the media is either water, dry air or inert gases. The operating conditions must be carefully considered to ensure the fitting is suitable for the intended application. The T-piece is not certified for potable water use and should not be installed in systems where drinking water is transported. It is designed for use in permanently pressurised systems and is not suitable for open or atmospheric systems.

The operating temperature range from -20 °C to +120 °C allows for use in both cold and hot applications, while the maximum pressure rating of 16 bar ensures compatibility with high-pressure systems. The nominal pressure rating PN 16 is a key factor in system sizing and must be matched with other components to maintain system integrity. The material, carbon galvanized steel, provides corrosion resistance and mechanical strength, making it suitable for long-term use in industrial and heating environments.

Installation and connection

The T-piece is designed for press-to-press connection using compatible Type M jaws. The connection sizes are 108 mm, 76.1 mm and 108 mm, and must be matched with corresponding pipe diameters. During installation, it is essential to ensure that the molding indicator is fully engaged and that the fitting is properly seated. Common installation mistakes include using mismatched jaw types or failing to check the molding indicator, which can lead to leaks or reduced system efficiency. The fitting must be installed in a straight line to prevent stress on the joints and to ensure even pressure distribution.

Compatibility and accessories

This T-piece is compatible with other IVAR.IVC41 and IVAR.IVC44 fittings and pipes of the same material. It is not compatible with systems requiring surface coating limiting agents or where potable water is used. No additional accessories are required for installation, but it is important to ensure that all components are from the same system to maintain compatibility. Installers should verify that the system includes all necessary components such as valves, pressure regulators and insulation materials for optimal performance.

Technical background for designers

The T-piece operates by creating a branch connection in a pressurised system. The EPDM O-ring ensures a tight seal between the fitting and the pipe, preventing leaks. The carbon galvanized steel construction provides resistance to corrosion and mechanical damage, making it suitable for a wide range of environments. The operating principle relies on the press-fit connection, which eliminates the need for welding or threading. The service life and efficiency of the fitting depend on the system's operating conditions, including temperature, pressure and media type. Proper system design and regular maintenance are essential to ensure long-term performance.

Service and operation

No specific service intervals are required for this T-piece. However, it is important to periodically inspect the fitting for signs of wear, corrosion or leakage. The molding indicator should be checked to ensure that the connection remains secure. If any issues are detected, the fitting should be replaced immediately to prevent system failure. The fitting is not designed for disassembly and should be replaced as a complete unit if necessary.
