Press reducer with one spigot end IVAR.IVN412 88.9-76.1 mm, stainless steel AISI 304

Product detailed description

The IVAR.IVN412 88.9-76.1 mm reducer made of stainless steel AISI 304 (1.4301) is a press fitting that takes the line from 88.9 mm down to 76.1 mm in a single step. The plain spigot end with a diameter of 88.9 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 76.1 mm pipe. The overall length of the reducer is 158 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 manufacturer supplies the LBP O-ring and the coloured press indicator only for sizes 15 to 54 mm, so the 76.1 mm socket does not have them – with a joint of this size, pressing is checked visually.

Both joints – the 76.1 mm socket and the 88.9 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 88.9-76.1 mm reducer connected?
The 76.1 mm pipe is pushed into the reducer's socket and pressed. The plain 88.9 mm end is inserted into the press socket of another 88.9 mm fitting and pressed together with it.

Which pressing jaws do I need?
Both joints – the 76.1 mm socket and the 88.9 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.

Does the reducer have a press indicator?
No. The orange strip and the LBP O-ring are supplied only for sizes 15 to 54 mm; with the 76.1 mm socket, pressing is checked visually.
