T-piece 90° - unambiguous - N - 88,9mm IVAR.IVN40

Product detailed description

This 90° T-piece is commonly used in residential and commercial building installations, including heating systems, sanitary plumbing, fire sprinkler systems, and industrial applications. It is suitable for press-fit connections and is designed to handle a range of fluids and gases under pressure. The component is particularly useful in systems where directional changes are required without the use of additional fittings or valves. It is often found in HVAC systems, solar installations, and compressed air systems, where reliable sealing and corrosion resistance are essential.

Installers working on these types of systems will benefit from the compact and robust design of this T-piece. It is ideal for use in environments where the system is exposed to fluctuating temperatures and requires a durable connection. The press-fit system ensures a secure and leak-free connection, provided the installation is performed correctly and the specified dimensions are followed.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN40.89
Brand	IVAR

The operating temperature range of -20°C to +85°C, with a maximum of +120°C, makes this T-piece suitable for a wide range of applications, including heating and solar systems. The nominal pressure rating of PN16 indicates the maximum pressure the component can handle under normal operating conditions. These parameters are essential for sizing and selecting the correct component for a specific system, ensuring compatibility with the overall pressure and temperature requirements.

Installation and connection

Installation of this T-piece requires a press tool compatible with the press-fit system. The connection sizes must be verified to ensure compatibility with the adjacent pipes and fittings. The installer should check that the press marks are correctly aligned and that the indicator reaches the specified 54 mm dimension. Common installation mistakes include incorrect press depth, misalignment of the components, and failure to verify the sealing integrity after installation. It is important to follow the manufacturer's guidelines to avoid leaks and ensure long-term performance.

Compatibility and accessories

This T-piece is compatible with other press-fit components from the same manufacturer, including pipes and fittings of the same material and connection type. It is typically used in conjunction with stainless steel pipes and other press-fit fittings. No additional accessories are required for standard installation, provided the system is designed with compatible components. Related products include other T-pieces and elbows from the IVAR IVN40 and IVN41 series.

Technical background for designers

The T-piece operates on the principle of mechanical compression, where the press-fit connection ensures a tight and durable seal. The EPDM O-ring provides a flexible and reliable sealing surface, adapting to minor surface imperfections. The integration into the system depends on the overall pressure and temperature conditions, as well as the compatibility of the adjacent components. The service life and efficiency of the component are influenced by the quality of the installation and the operating conditions of the system.

Service and operation

Regular inspection of the press-fit connections is recommended to ensure continued sealing performance. The installer should check for signs of wear, deformation, or leakage, particularly in areas exposed to high pressure or temperature fluctuations. No specific service intervals are provided in the technical data, but any issues should be addressed promptly to prevent system failure. The component is designed for long-term use with minimal maintenance, provided it is installed correctly and operated within the specified parameters.
