T-piece 90° - unambiguous - N - 108mm IVAR.IVN40

Product detailed description

This 90° T-piece is commonly used in residential and commercial building systems for the distribution of fluids in heating, plumbing and industrial applications. It is suitable for installation in systems such as sanitary water supply, fire sprinklers, solar thermal circuits and inert gas lines. The fitting is designed for use with press-fit stainless steel piping systems, ensuring a secure and leak-free connection when installed correctly. It is particularly useful in systems where space constraints require angular connections and directional changes in the piping layout.

Installers working in HVAC, plumbing and industrial sectors will find this component essential for creating branch connections in press-fit stainless steel systems. The T-piece is typically used in environments where resistance to corrosion and high temperatures is required, such as in underfloor heating systems, solar installations and industrial gas lines. It is also suitable for use in systems with intermittent high-temperature operation, such as steam or hot water circuits.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN40.108
Brand	IVAR

The operating temperature range of -20 °C to +120 °C allows the fitting to be used in both cold and hot water systems, as well as in industrial environments with fluctuating temperatures. The nominal pressure rating of PN 16 ensures compatibility with systems operating at moderate pressures. These parameters are essential for determining the suitability of the T-piece for specific applications and for ensuring correct sizing in system design.

Installation and connection

The T-piece is designed for press-fit installation using compatible stainless steel pipe and press tools. The connection size is 108 mm, and the fitting must be pressed to a depth of 54 mm to ensure a secure and leak-free joint. During installation, it is important to verify that the pipe is correctly sized and that the O-ring is in place and undamaged. Common installation errors include insufficient pressing depth, misalignment of the pipe and fitting, and failure to use the correct press tool for the specified pipe diameter. To avoid leaks, the installer must ensure that the press tool is correctly calibrated and that the indicator mark is fully engaged during pressing.

Compatibility and accessories

This T-piece is compatible with press-fit stainless steel piping systems using 1.4404 stainless steel tubing. It requires the use of EPDM O-rings for sealing and must be installed with the appropriate press tools. Additional components such as straight pipe sections, elbows and other branch fittings may be required to complete the system. No specific related products are listed for this model.

Technical background for designers

The T-piece functions as a branch connection in press-fit stainless steel systems, allowing for the distribution of fluids in multiple directions. The use of 1.4404 stainless steel ensures resistance to corrosion and high-temperature environments, making it suitable for a wide range of applications. The EPDM O-ring provides a flexible and durable seal that remains effective across the operating temperature range. The design of the fitting allows for a compact and reliable connection, which is essential in systems where space is limited. The integration of the T-piece into the system must consider the overall pressure and temperature conditions to ensure long-term performance and system efficiency.

Service and operation

No specific service intervals are provided for this component. However, during routine system checks, it is recommended to inspect the T-piece for signs of wear, corrosion or leakage. If any issues are detected, the fitting should be replaced to maintain system integrity. The O-ring should be checked for damage or degradation, particularly in high-temperature environments, as this can affect the seal's effectiveness over time.

Frequently asked questions
