Connector union with female thread IVAR.IVN462 42 mm – Rp 6/4", press, stainless steel AISI 304
Code: IVN462.4216Product detailed description
The IVAR.IVN462 42 mm – Rp 6/4" connector union is the transition piece between a pressed stainless steel pipeline and a threaded connection. The press end takes the 42 mm pipe, while the other end has an Rp 6/4" female thread for valves and fittings with a male thread. The two parts are held together by a union nut with a flat gasket, so the joint can be taken apart when needed. The manufacturer specifies AISI 304 stainless steel (1.4301) and, for this type, brass as well; the pressed joint is sealed by an EPDM O-ring. The overall length of the union is 82 mm and the Z dimension 33 mm.
Areas of use
The union belongs in closed heating and cooling systems and solar circuits, and is also used in lines for compressed air, vacuum, inert and technical gases, technical and process liquids, or waste water and rainwater. It is not suitable for drinking water.
Operating values
- pressure up to PN 16, vacuum down to -0.8 bar (absolute pressure 0.2 bar)
- temperature from -20 °C to +85 °C, maximum +120 °C
- antifreeze mixture up to a concentration of 50 %
Installation
The pipe is pressed with M-profile press jaws. The patented LBP (Leak Before Press) O-ring with its kinked shape lets liquid through during the pressure test if the joint has been left unpressed, and the orange strip shows the pressing status. To seal the thread, the system instructions recommend chloride-free materials, for example chloride-free Teflon tape. Installation should be carried out by a professional according to the system manufacturer's instructions; before commissioning the heating, the system must be flushed, and the manufacturer recommends GEL.LONG LIFE 100 for water treatment.
The IVAR.IVN462 range covers sizes from 15 mm – Rp 1/2" to 54 mm – Rp 2".

Frequently asked questions
What can be connected with the IVAR.IVN462 42 mm – Rp 6/4" union?
A valve or fitting with a male thread is screwed into the Rp 6/4" female thread, and the other end is pressed onto a 42 mm stainless steel pipe. The union is intended, for example, for closed heating and cooling systems.
What should the threaded joint be sealed with?
The instructions for the stainless steel press system recommend chloride-free sealing materials – for example chloride-free Teflon tape or hemp with a chloride-free sealing paste.
How can an unpressed joint be recognised?
The LBP O-ring with its kinked profile lets liquid through during the pressure test as long as the joint is not pressed, and the orange strip signals pressing. Pressing is done with M-profile jaws.
Is the union suitable for drinking water?
No, the union bears a symbol indicating that it is not suitable for drinking water. It is used in closed heating and cooling circuits, solar systems, and for compressed air or technical gases.
