90° reduced T-piece IVAR.IVN441 76.1-35-76.1 mm, pressing type, stainless steel AISI 304
Code: IVN441.763576Product detailed description
Tee 90° IVAR.IVN441 76,1-35-76,1 mm is a reduced press fitting elbow made of stainless steel AISI 304 (material no. 1.4301). The running bores are 76.1 mm, and the branch is 35 mm – this fitting allows you to connect a smaller branch to the main pipe without further reduction. All three ends are press fittings (press × press × press) and are sealed with EPDM O-rings. The overall length of the fitting is 232 mm.
Where the Tee is suitable
- closed heating and cooling systems, solar circuits
- compressed air distribution, vacuum systems, inert and technical gases
- technical and operational liquids in industry
- drainage of waste and rainwater
The fitting is not suitable for potable water – this is also indicated by a symbol printed together with the logo, AISI 304 material, dimensions, and traceability code directly on the fitting.
Operating values
- maximum operating pressure PN 16, vacuum down to -0.8 bar (absolute pressure 0.2 bar)
- temperature from -20 °C, up to +85 °C in normal operation, maximum +120 °C
- anti-freeze mixture with a concentration of up to 50 %
Pressing and joint inspection
The 35 mm branch is equipped with a patented LBP (Leak Before Press) O-ring with a broken profile – an unpressed joint will leak during pressure testing – and an orange stripe as an indicator of pressing. These features are provided by the manufacturer only for sizes from 15 to 54 mm; the running bores of 76.1 mm do not have them, so their pressing must be checked particularly carefully.
Pressing is done using jaws with contour M. Warning: installation must be carried out by a qualified person in accordance with the installation and use instructions issued by the system manufacturer. Before commissioning the heating system, the manufacturer strongly recommends flushing the entire system; for water treatment, the preparation GEL.LONG LIFE 100 is recommended.
In the IVAR.IVN441 range, you will also find other combinations of dimensions from 18-15-18 mm up to 108-88.9-108 mm.

Frequently asked questions
Is the IVAR.IVN441 76.1-35-76.1 mm tee suitable for potable water?
No, stainless steel fittings of this series made of AISI 304 are not suitable for potable water and also carry a symbol indicating this. They are used, for example, in closed heating and cooling circuits, solar systems, or for compressed air.
Which pipes are connected to this tee?
Pipes of 76.1 mm diameter are pressed into the two running bores, and a pipe of 35 mm diameter is connected to the branch. All three ends are press fittings (press × press × press).
Which tool is used to press the tee?
Pressing tools with jaws of contour M. The joints must be made by a qualified person in accordance with the installation and use instructions from the system manufacturer.
How can I tell if a joint was not pressed properly?
The 35 mm branch is equipped with an LBP O-ring, which reveals an unpressed joint by a leak during pressure testing, and an orange indicator stripe. The running bores of 76.1 mm do not have these features, so their pressing must be checked particularly carefully.
