T-piece 90° - internally threaded - N - 108-Rp2"-108mm IVAR.IVN42

Product detailed description

This 90° T-piece with internal thread is commonly used in heating, sanitary, and industrial piping systems. It is designed for applications requiring reliable connections under moderate pressure and temperature conditions. The fitting is suitable for use in residential, commercial and industrial buildings, particularly in systems such as heating circuits, fire sprinklers, compressed air lines, solar thermal installations, and inert gas systems. Installers working on these systems will find this component ideal for branching pipe runs while maintaining system integrity.

The T-piece is manufactured using high-grade stainless steel, ensuring resistance to corrosion and durability over time. Its internal thread allows for secure and leak-free connections when properly installed. The EPDM sealing ring ensures compatibility with a wide range of fluids and gases, making it suitable for diverse applications. The fitting is intended for use in press-to-fit systems, where one side is pressed and another is threaded, allowing for flexible integration into existing or new installations.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN42.10820108
Brand	IVAR

The nominal pressure rating of PN 16 indicates that the fitting can handle pressures up to 16 bar at reference temperatures. The operating temperature range from -20 °C to +85 °C means the component is suitable for both cold and warm water systems, as well as low-temperature heating circuits. These parameters are essential for correctly sizing the fitting and ensuring compatibility with the system’s operating conditions.

Installation and connection

The installation process involves preparing the pipe ends, applying the correct press-fit tooling, and ensuring the internal thread is clean and undamaged. The connection sizes include press x thread x press, with one side requiring a press-fit connection and the other a threaded one. During installation, it is crucial to verify that the O-ring is correctly seated and that the fitting is fully inserted into the pipe until the seating indicator aligns with the 54 mm mark. Common installation errors include insufficient pressing depth, misalignment of the O-ring, or failure to clean the internal thread before assembly.

Compatibility and accessories

This T-piece is compatible with standard press-fit systems using stainless steel piping and threaded components. It works well with other fittings and valves of similar material and pressure ratings. To ensure a complete and functional installation, additional components such as straight couplings, elbows, or valves may be required depending on the system layout. As no alternative products are listed, it is recommended to refer to the manufacturer’s technical documentation for further compatibility details.

Technical background for designers

The 90° T-piece functions by providing a directional branch in a piping system, allowing for the distribution of fluids or gases. The stainless steel body offers high resistance to corrosion and mechanical stress, making it suitable for long-term use in various environments. The EPDM sealing ring ensures a tight and durable seal, preventing leaks even under fluctuating pressure and temperature conditions. The fitting integrates into the system by connecting to press-fit pipes on one side and threaded components on the other. The service life and efficiency depend on proper installation, adherence to pressure and temperature limits, and regular inspection for wear or damage.

Service and operation

No specific service intervals are provided for this component. Routine checks should focus on the integrity of the connections, particularly the seating of the O-ring and the absence of leaks. Any signs of corrosion, wear, or leakage should be addressed promptly to prevent system failure. The fitting is designed for long-term use with minimal maintenance, provided it is installed according to the manufacturer’s guidelines.

Frequently asked questions

Can this T-piece be used in solar thermal systems?
Yes, it is suitable for solar thermal systems due to its resistance to thermal cycling and compatibility with fluids used in such systems.

Is it compatible with press-fit stainless steel pipes?
Yes, it is designed for press-fit stainless steel pipes on one side and threaded connections on the other.

What is the maximum operating temperature?
The maximum operating temperature is +85 °C, with a short-term tolerance up to +120 °C.

How is the O-ring secured during installation?
The O-ring is seated in a groove inside the fitting and compressed when the pipe is inserted, ensuring a leak-free connection.
