IVAR.IVN412 76.1-54 mm one-side slip-on reducer, stainless steel AISI 304

Product detailed description

The reduction IVAR.IVN412 76,1-54 mm made of stainless steel AISI 304 (1.4301) is a press-fit system fitting, which allows a transition from the dimension 76,1 mm to 54 mm in one step. The smooth push-in end with a diameter of 76,1 mm is inserted into the press-fit socket of another fitting of the same size, while the opposite side has a press-fit socket with an EPDM O-ring for the 54 mm pipe. The total length of the reduction is 142 mm.

For which types of systems is it suitable

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

The reduction is not suitable for potable water – this is also indicated by the symbol in the fitting designation.

Operating limits

• pressure up to PN 16, vacuum down to -0,8 bar (absolute pressure 0,2 bar)
• operating temperature from -20 °C to +120 °C
• anti-freeze mixture with a maximum concentration of 50 %

Installation and inspection of the press-fit

The 54 mm socket is equipped with an LBP (Leak Before Press) O-ring with a segmented profile – an unpressed joint will leak during pressure testing and thus cannot be overlooked. Additionally, there is an orange stripe on the socket, which will tear during pressing and can be removed by hand.

Both joints – the 54 mm socket and the push-in end of 76,1 mm in the connecting fitting – are pressed using chain jaws with profile M and at least 3 segments. Insert the pipe all the way to the stop and mark its position with a marker. The O-ring may only be moistened with water, never with oil or grease, and each joint is pressed only once.

For large diameters of 76,1 to 108 mm, the manufacturer recommends fixing the pipes and fittings with mounting clamps before pressing to ensure the joint remains precisely aligned.

Warning: Pressed joints must be made by a qualified person according to the IVAR.PRESS FITTING SYSTEM instructions. Before starting the heating system, the manufacturer recommends flushing the entire system.

Technical parameters

Frequently asked questions

Can the IVAR.IVN412 reduction be used for potable water?
No, fittings made of AISI 304 steel in this series are not suitable for potable water. They can be used, for example, in closed heating and cooling circuits, solar systems, or for compressed air.

How is the 76,1-54 mm reduction connected?
The 54 mm pipe is inserted into the press-fit socket of the reduction and pressed. The smooth 76,1 mm end is inserted into the press-fit socket of another 76,1 mm fitting and pressed together with it.

Which press-fit jaws are needed?
Both joints – the 54 mm socket and the push-in end of 76,1 mm in the connecting fitting – are pressed using chain jaws with profile M and at least 3 segments. Jaws with profile V must not be used with this system.

How can I recognize an unpressed joint?
The 54 mm socket has an LBP O-ring, which will leak fluid during pressure testing if the joint is not pressed. An unpressed socket is also indicated by an intact orange stripe.
