90° single-direction T-piece PRESS IVAR.IVN440 – stainless steel AISI 304, 54 mm

Product detailed description

IVAR.IVN440 – 54 mm (code IVN440.54) is a one-sided, i.e. equilateral T-piece 90° made of stainless steel AISI 304 (1.4301). The run and the branch end with a press-on neck (PRESS × PRESS × PRESS) for a tube with an outer diameter of 54 mm, so you can branch off a perpendicular branch of the same dimension from the running pipe.

For which systems

• closed heating and cooling systems, solar circuits
• compressed air and vacuum systems
• inert and technical gases, technical and operational liquids
• industrial applications, waste and rainwater

This T-piece is not suitable for potable water. Its body is marked with the AISI 304 logo, dimensions, traceability code and a symbol indicating unsuitability for potable water.

Pressing for size 54 mm

For diameters from 42 to 108 mm, the manufacturer allows only chain jaws with profile M with at least three segments, usually with a transition adapter; pressing with standard single-piece jaws is not accepted. Profile V is prohibited at any diameter. For the size 54 mm, a pressing tool with medium force (up to 40 kN) is required, which according to the instructions presses diameters up to 54 mm. Inspection is facilitated by an orange stripe on the neck, which indicates an unpressed connection, and an O-ring LBP (Leak Before Press) with a broken profile – as long as the connection is not pressed, liquid leaks from it during pressure testing.

Cut the tube perpendicularly to the axis, deburr it inside and outside and moisten the O-ring with water at most, never with oil or grease. Insert it with a slight twist until it reaches the stop, mark the position with a marker and press the connection on the first attempt.

Technical data

• maximum operating pressure PN 16, vacuum down to -0.8 bar (absolute pressure 0.2 bar)
• operating temperature -20 °C to +85 °C, maximum +120 °C
• anti-freeze mixture with a concentration of up to 50 %
• material: stainless steel AISI 304 (1.4301), sealing O-ring EPDM
• dimensions according to the drawing: L 142 mm, L1 74 mm, Z 34 mm, Z1 37 mm, I 71 mm

For a smaller or threaded branch, T-pieces IVAR.IVN441 (reduced) and IVAR.IVN442 (with internal thread) are available in the same range. Before starting the heating system, flush the entire system – IVAR recommends GEL.LONG LIFE 100 for treatment.

Technical parameters

Frequently asked questions

Can I use the IVAR.IVN440 T-piece for potable water distribution?
No. Fittings made of stainless steel AISI 304 in this range are not intended for potable water, as indicated by the symbol on their body. Use them in closed heating and cooling circuits, solar systems or for compressed air and technical gases.

Which pressing jaws do I need for size 54 mm?
Chain jaws with profile M with at least three segments, usually with a transition adapter. The manufacturer does not accept single-piece jaws for diameters from 42 mm and profile V is prohibited.

How can I tell that the connection is not yet pressed?
There is an orange indicator stripe on the neck and the LBP O-ring with a broken profile causes the unpressed connection to leak during pressure testing. An unpressed connection is thus immediately revealed.

Can a smaller branch be taken off from the IVAR.IVN440 54 mm T-piece?
No, it is a one-sided T-piece – all three necks have a diameter of 54 mm. For a smaller diameter branch, the reduced T-piece IVAR.IVN441 is available in the range.
