Press reducer with one spigot end IVAR.IVN412 76.1-54 mm, stainless steel AISI 304

Product detailed description

The IVAR.IVN412 76.1-54 mm reducer made of stainless steel AISI 304 (1.4301) is a press fitting that takes the line from 76.1 mm down to 54 mm in a single step. The plain spigot end with a diameter of 76.1 mm is inserted into the press socket of another fitting of the same size; on the opposite side, a press socket with an EPDM O-ring receives the 54 mm pipe. The overall length of the reducer is 142 mm.

Applications

• closed heating and cooling circuits, solar systems
• technical and process fluids, industrial applications
• compressed air, vacuum systems, inert and technical gases
• waste water and rainwater drainage

The reducer is not intended for drinking water – a symbol in the fitting's marking points this out as well.

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
• antifreeze at a concentration of max. 50 %

Installation and press check

The 54 mm socket is fitted with an LBP (Leak Before Press) O-ring with a broken profile – an unpressed joint leaks during the pressure test, so it cannot be overlooked. In addition, an orange strip sits on the socket; it tears when the joint is pressed and can be removed by hand.

Both joints – the 54 mm socket and the 76.1 mm spigot end in the socket of the adjoining fitting – are pressed with M-profile press chains with at least 3 segments. Push the pipe in up 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 from 76.1 to 108 mm, the manufacturer recommends fixing pipes and fittings with installation clamps before pressing so that the joint stays perfectly aligned.

Note: press joints must be made by a professional in line with the IVAR.PRESS FITTING SYSTEM instructions. Before starting up the heating system, the manufacturer recommends flushing the entire system.

Technical data

Frequently asked questions

Can the IVAR.IVN412 reducer be used for drinking water?
No, the AISI 304 steel fittings of this series are not intended for drinking 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 reducer connected?
The 54 mm pipe is pushed into the reducer's socket and pressed. The plain 76.1 mm end is inserted into the press socket of another 76.1 mm fitting and pressed together with it.

Which pressing jaws do I need?
Both joints – the 54 mm socket and the 76.1 mm spigot end in the socket of the adjoining fitting – are pressed with M-profile press chains with at least 3 segments. Jaws with V profile must not be used with this system.

How can I recognise an unpressed joint?
The 54 mm socket has an LBP O-ring that lets fluid escape during the pressure test if the joint has not been pressed. An intact orange strip also gives away an unpressed socket.
