T-piece 90° - reduced - N - 88,9-54-88,9mm IVAR.IVN41

Product detailed description

This reduced 90° T-piece is commonly used in residential and commercial buildings for the distribution of fluids in heating and plumbing systems. It allows for the branching of pipelines at right angles while maintaining hydraulic efficiency. The fitting is particularly suited for systems requiring high resistance to corrosion and chemical exposure, such as solar thermal circuits, fire suppression networks and industrial piping. Installers working with stainless steel press systems will find this component ideal for ensuring secure, leak-free connections in a variety of applications.

The T-piece is typically found in systems where space constraints require angled connections and where flow balance is critical. Its design supports the integration into closed-loop systems, ensuring even distribution and minimal turbulence. The fitting is often used in conjunction with other press fittings and straight pipe sections to create complex network layouts in compact environments.

Technical parameters

The nominal pressure rating of PN 16 indicates that the fitting is suitable for medium-pressure applications. The operational temperature range from -20 °C to +85 °C, with a maximum of +120 °C, means it can handle both cold and hot media. These parameters are essential for selecting the correct fitting in accordance with system design requirements and environmental conditions.

Installation and connection

Installation requires the use of a press tool compatible with stainless steel press connections. The T-piece has three press ends with diameters of 88.9 mm, 54 mm and 88.9 mm. The press tool must apply sufficient force to compress the ferrule around the tube, creating a watertight seal. The EPDM O-ring enhances the seal between the fitting and the pipe.

• Ensure the tube is clean, free from burrs and cut to the correct length.
• Verify that the ferrule is correctly positioned before pressing.
• Use a calibrated press tool to avoid under- or over-pressing.
• After pressing, inspect the fitting for deformation or misalignment.

Common installation errors include using the wrong tool, failing to check the alignment of the ferrule, or not verifying the press depth. Always confirm the fit after installation and perform a pressure test to detect leaks.

Compatibility and accessories

This T-piece is designed for use with stainless steel press tubes of the specified outer diameters. It is compatible with other IVAR press fittings of the same material and connection type. For complete system integration, ensure that all components are from the same manufacturer and series to maintain consistency in performance and sealing properties.

Additional components such as straight pipes, elbows and valves should be selected based on the system layout and flow requirements. No specific accessories are required unless additional support or insulation is needed in the installation environment.

Technical background for designers

The T-piece operates by allowing fluid to flow through two perpendicular branches while maintaining a continuous flow path. The stainless steel construction provides high resistance to corrosion and mechanical stress, making it suitable for aggressive environments. The EPDM O-ring ensures a reliable seal under varying pressure and temperature conditions.

The material properties of 1.4404 stainless steel include good formability, weldability and resistance to chloride-induced pitting. This makes it ideal for use in both indoor and outdoor systems exposed to moisture or chemical agents. The integration of the fitting into the system depends on the overall layout, flow rates and pressure drop calculations.

The service life and efficiency of the T-piece are influenced by proper installation, regular inspection and the absence of mechanical stress on the joints. Avoid bending or twisting the fitting after installation to prevent premature failure.

Service and operation

During operation, the fitting requires no active maintenance. However, periodic inspections should be carried out to check for signs of wear, corrosion or leakage. Any visible damage or deformation should be addressed immediately by replacing the affected component.

Checkpoints include verifying the integrity of the press connections, ensuring the system pressure remains within the rated limits and confirming the absence of external stress on the fitting. If a leak is detected, the system should be depressurised and the fitting inspected for damage or improper installation.

Frequently asked questions
