T-piece 90° - reduced - N - 42-28-42mm IVAR.IVN41

Product detailed description

Stainless steel T-pieces are essential components in press-fit piping systems for heating, plumbing, and industrial applications. They are commonly used in residential and commercial buildings to connect and redirect fluid flow in closed-loop systems. Installers working on central heating, hot water distribution, or fire suppression systems frequently use these fittings to create branch connections in press-fitted stainless steel piping. The 90° angle of this T-piece allows for directional changes in compact spaces, while the reduced cross-section ensures compatibility with different pipe diameters in the same system.

Correct selection of T-pieces is critical for maintaining system integrity and performance. The operating temperature range and pressure rating must align with the system's design conditions to prevent leaks or failures. This T-piece is suitable for systems with moderate thermal and hydraulic demands, where directional flexibility and material durability are required.

Technical parameters

The nominal pressure rating of PN 16 indicates the maximum pressure the fitting can withstand at 20°C. The operating temperature range from -20°C to +120°C allows for use in both cold and hot water systems, as well as in heating circuits. The stainless steel body provides resistance to corrosion and scaling, while the EPDM O-ring ensures a tight seal across the connection. These parameters are essential for determining compatibility with the system's operating conditions and for ensuring long-term performance.

Installation and connection

This T-piece is designed for press-fit installation using compatible stainless steel pipes and press tools. The connection sizes are 42 mm, 28 mm, and 42 mm, with press-fit connections on all three ends. Installers should ensure that the pipe ends are clean and free of burrs before inserting them into the fitting. The press tool must be correctly aligned with the fitting to ensure a uniform and secure connection. Common installation errors include misalignment of the tool, insufficient press force, or using incorrect pipe diameters, which can lead to leaks or reduced system efficiency.

Compatibility and accessories

This T-piece is compatible with press-fit stainless steel piping systems using the same material grade and sealing technology. It is intended for use with EPDM O-rings and press tools designed for the specified pipe diameters. When installing, ensure that all connected pipes are of the same material and press-fit standard. No additional accessories are required for standard installation, but press tools and sealing rings should be kept on-site for maintenance or replacement.

Technical background for designers

The T-piece functions as a directional and branching component in press-fit piping systems. The stainless steel body provides high mechanical strength and resistance to thermal expansion, making it suitable for both low-temperature and high-temperature applications. The EPDM O-ring ensures a flexible and durable seal, compensating for minor misalignments and thermal movement. The fitting's integration into the system depends on the system's hydraulic design and the need for branch connections. The material properties and connection method ensure a long service life, provided that the system is designed within the specified operating conditions.

Service and operation

During operation, the T-piece requires no active maintenance. However, periodic visual inspections are recommended to check for signs of wear, corrosion, or leakage. If a leak is detected, the fitting should be isolated and inspected for damage to the O-ring or press connection. No specific service intervals are required, as the fitting is designed for long-term use under normal operating conditions. Any replacement should be carried out by qualified personnel using the correct tools and procedures.
