T-piece 90° - internally threaded - N - 35-Rp3/4"-35mm IVAR.IVN42

Product detailed description

This 90° T-piece with internal thread is commonly used in heating, plumbing, and industrial systems. It enables the branching of fluid flow in pipelines and is suitable for both new installations and system modifications. Installers often use it in domestic and commercial buildings for water supply, heating circuits, and fire protection systems. The component is designed for environments where corrosion resistance and durability are essential, such as in wet rooms, boiler houses, and chemical processing areas.

The stainless steel construction ensures long-term reliability in aggressive media and high-temperature conditions. The EPDM sealing ring provides a tight connection when properly compressed during installation. This fitting is particularly suited for applications requiring a robust and leak-free joint under variable thermal and mechanical loads.

Technical parameters

The nominal pressure rating of PN16 indicates the maximum pressure the fitting can handle under normal operating conditions. The temperature range from -20°C to +120°C allows for use in both cold and hot water systems. These parameters are essential for determining the suitability of the fitting in specific system designs and ensuring compatibility with other components.

Installation and connection

Installation requires pressing the fitting onto the pipe using a certified press tool. The internal thread connects to another threaded component, such as a valve or meter. Before pressing, ensure the pipe ends are clean and free from burrs. Check that the press tool is correctly aligned to avoid misalignment and uneven compression.

Verify that the press mark reaches the required depth of 54 mm as indicated by the visual marker. After installation, perform a pressure test to confirm the integrity of the joint. Always follow the manufacturer’s guidelines for press tools and installation procedures to maintain system performance and safety.

Compatibility and accessories

This T-piece is compatible with other IVAR press fittings and threaded components. To complete the installation, additional items such as press tools, sealing rings, and threaded adapters may be required. Ensure all components are from the same system to maintain compatibility and prevent leakage. For complex systems, consider using expansion joints or support brackets to manage thermal expansion and vibration.

Technical background for designers

The 90° T-piece functions by splitting or combining fluid flow in a pipeline. The stainless steel body resists corrosion and maintains structural integrity under high temperatures. The EPDM O-ring provides a flexible seal that adapts to minor misalignments. When integrated into a system, the fitting should be positioned to allow for easy access during maintenance. The material’s resistance to scaling and pitting makes it ideal for water and steam systems. The pressure and temperature limits are critical for system design and must be considered alongside pump specifications and pipe dimensions.

Service and operation

During operation, inspect the joint visually for signs of wear or leakage. Check the press mark regularly to ensure it remains intact and undistorted. If the system is exposed to extreme temperatures or high vibration, reinforce the installation with supports or insulation. There are no scheduled service intervals for this component unless specified in the system’s maintenance plan. Any issues with the seal should be addressed immediately by replacing the O-ring or the entire fitting.

Frequently asked questions

Can this T-piece be used in solar heating systems?
Yes, it is suitable for solar heating systems due to its temperature range and resistance to thermal cycling.

Is the EPDM O-ring compatible with acidic or alkaline media?
Yes, EPDM is generally resistant to mild acidic and alkaline solutions, making it suitable for many water-based systems.

What press tool is recommended for this fitting?
A certified IVAR press tool should be used to ensure proper compression and avoid damage to the fitting.

How is the correct installation depth confirmed?
The fitting includes a visual indicator that shows when the press mark reaches the required depth of 54 mm.
