T-piece 18 x 22 x 18

Product detailed description

This T-piece is commonly used in closed pressurised systems for central heating, refrigeration, fire suppression, and industrial air or gas distribution. It is ideal for installations where a branch connection is required in a straight run of piping. The fitting is designed for use with press-fit systems, ensuring a secure and leak-free connection without the need for welding or threading. It is particularly suited for environments where high-pressure resistance and a wide operating temperature range are essential.

Typical applications include residential and commercial heating systems, fire water supply ducts, air-conditioning systems, and solar piping. The T-piece is also suitable for dry air and inert gas systems in industrial settings. The fitting is intended for use with press-to-fit tools compatible with Type M jaws, ensuring accurate and repeatable installation.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.094 kg
Code	IVC44.182218
Brand	IVAR

The T-piece is rated for a nominal pressure of PN16 and can withstand operating pressures up to 16 bar. It is suitable for use in systems with temperatures ranging from -20°C to +120°C. These parameters are essential for determining the suitability of the fitting for specific system conditions and for ensuring correct sizing and selection during design and installation.

Installation and connection

To install the T-piece, ensure the pipe ends are clean and free of debris. Use a press-fit tool compatible with Type M jaws to compress the fitting around the pipe. The fitting has dimensions of 18 x 22 x 18 mm and is designed for press-to-fit connections on all three ends. During installation, verify that the molding indicator is fully engaged and that the tool is correctly aligned with the fitting. Common installation errors include misalignment of the tool, insufficient compression, or using incompatible tools, which can lead to leaks or reduced system performance.

Compatibility and accessories

This T-piece is compatible with press-fit systems using EPDM O-rings and is intended for use with carbon galvanized steel piping. It is not certified for drinking water applications. For a complete installation, ensure that all connected components are from the same press-fit system and that the correct tools are available for compression. Additional components such as straight pipes, elbows, and valves should be selected based on the system layout and pressure requirements.

Technical background for designers

The T-piece operates by creating a branch connection in a pressurised system using a mechanical compression joint. The material, carbon galvanized steel, provides resistance to corrosion and mechanical damage while maintaining structural integrity under pressure. The EPDM O-ring ensures a tight seal and is resistant to a wide range of temperatures and media. The fitting integrates into the system by aligning with the hydraulic and thermal requirements of the application. The service life and efficiency of the fitting are influenced by the quality of installation, the compatibility of connected components, and the operating conditions of the system.

Service and operation

Regular inspection of the T-piece is recommended to ensure the integrity of the press-fit connection. Check for signs of wear, corrosion, or leaks, particularly at the connection points. The fitting does not require scheduled maintenance, but any damage or degradation should be addressed immediately to prevent system failure. During operation, ensure that the system pressure and temperature remain within the specified limits to avoid overstressing the fitting.
