90° reduced T-piece IVAR.IVN441 76.1-54-76.1 mm, crimped, stainless steel AISI 304

Product detailed description

Tee 90° IVAR.IVN441 76,1-54-76,1 mm is a reduced pressed elbow made of stainless steel AISI 304 (material no. 1.4301). The running branches have a dimension of 76.1 mm, the perpendicular branch is 54 mm – this elbow allows you to connect a smaller branch to the main pipe without further reduction. All three ends are pressed (press × press × press) and sealed with EPDM O-rings. The overall length of the elbow 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 elbow is not suitable for potable water – this is also indicated by a symbol, which is together with the AISI 304 logo, dimensions and traceability code marked directly on it.

Operating values

• maximum operating pressure PN 16, vacuum down to -0.8 bar (absolute pressure 0.2 bar)
• temperature from -20 °C, in normal operation up to +85 °C, maximum +120 °C
• anti-freeze mixture with a concentration of up to 50 %

Pressing and joint inspection

The 54 mm branch has a patented LBP (Leak Before Press) O-ring with a broken profile – an unpressed joint will leak fluid during a pressure test – and an orange stripe as an indicator of pressing. The manufacturer includes these features only for sizes from 15 to 54 mm; the running branches of 76.1 mm do not have them, so their pressing must be checked especially carefully.

For pressing, use jaws with contour M. Warning: installation must be carried out by a qualified person according to 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 76.1-54-76.1 mm tee suitable for potable water?
No, the stainless steel elbows 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 branches, and a pipe of 54 mm diameter into the perpendicular branch. All three ends are pressed (press × press × press).

What tool is used to press the tee?
Pressing tools with jaws of contour M. The joints must be made by a specialist according to the installation and use instructions from the system manufacturer.

How can I tell if a joint remains unpressed?
The 54 mm branch has an LBP O-ring, which reveals an unpressed joint by a leak during a pressure test, and an orange indicator stripe. The 76.1 mm running branches do not have these features, so their pressing must be checked especially carefully.
