Reducing tee 90° press fitting IVAR.IVN441 42-35-42 mm, stainless steel AISI 304
Code: IVN441.423542Product detailed description
The IVAR.IVN441 42-35-42 mm 90° tee is a reducing press fitting made of AISI 304 stainless steel (material no. 1.4301). The run sockets are 42 mm and the perpendicular branch 35 mm – so a smaller branch line can be connected to the main pipe without an additional reducer. All three ends are press connections (press × press × press) sealed with EPDM O-rings. The overall length of the fitting is 118 mm.
Applications
- closed heating and cooling systems, solar circuits
- compressed air networks, vacuum systems, inert and technical gases
- technical and process fluids in industry
- drainage of waste water and rainwater
The fitting is not suitable for drinking water – this is also indicated by a symbol marked directly on the fitting together with the AISI 304 logo, the size and the traceability code.
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
- antifreeze mixture with a concentration of no more than 50 %
Pressing and joint inspection
The sockets at all three ends are fitted with the patented LBP (Leak Before Press) O-ring with an angled profile: as long as the joint is not pressed, liquid escapes from it during the pressure test, so the fault is detected before commissioning. In addition, an orange colour band indicates the pressing.
Pressing is done with M-profile press jaws. Note: installation must be carried out by a qualified person in accordance with the installation and operating instructions issued by the system manufacturer. Before commissioning the heating system, the manufacturer strongly recommends flushing the entire system; for water treatment it recommends the product GEL.LONG LIFE 100.
The IVAR.IVN441 range also includes other size combinations, from 18-15-18 mm up to 108-88.9-108 mm.

Frequently asked questions
Can the IVAR.IVN441 42-35-42 mm tee also be used for drinking water?
No, the AISI 304 stainless steel fittings in this range are not suitable for drinking water and 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?
A 42 mm pipe is pressed into each of the two run sockets and a 35 mm pipe into the perpendicular branch. All three ends are press connections (press × press × press).
Which tool is used to press the tee?
A pressing tool with M-profile press jaws. The joints should be made by a professional in accordance with the system manufacturer's installation and operating instructions.
How can I tell that a joint has been left unpressed?
All sockets have an LBP O-ring that lets liquid through during the pressure test if the joint is not pressed. In addition, an orange colour band indicates the pressing.
