IVAR.IVN462 22 mm – Rp 3/4" internal thread compression fitting, stainless steel AISI 304
Code: IVN462.2234Product detailed description
Connecting sleeve IVAR.IVN462 22 mm – Rp 3/4" is a transition piece between a crimped stainless steel pipe and a threaded connection. The crimping end accepts a 22 mm tube, while the opposite end has an internal Rp 3/4" thread for fittings and valves with an external thread. Both parts are held together by a nut with a flat gasket, so the joint can be disassembled if necessary. The manufacturer specifies stainless steel AISI 304 (1.4301) and for this type of specification also brass; the crimped joint is sealed with an EPDM O-ring. The total length of the sleeve is 63 mm, dimension Z 28 mm.
Fields of application
The sleeve belongs to closed heating and cooling systems and solar circuits, and can also be used in compressed air, vacuum, inert and technical gas, technical and operational liquids, or waste and rainwater distribution systems. It is not suitable for potable water.
Operating parameters
- pressure up to PN 16, vacuum down to -0.8 bar (absolute pressure 0.2 bar)
- temperature -20 °C to +85 °C, maximum +120 °C
- antifreeze mixture up to 50 % concentration
Installation
The tube is crimped using jaws with contour M. The patented LBP (Leak Before Press) O-ring with a broken shape will release liquid during a pressure test if the joint remains uncrimped, and the orange stripe indicates the crimping status. For sealing the thread, the system manual recommends materials without chlorides, for example, a chloride-free Teflon tape. Installation should be carried out by a qualified person according to the system manufacturer's instructions; before putting the heating system into operation, the system should be flushed, and for water treatment, the manufacturer recommends GEL.LONG LIFE 100.
The IVAR.IVN462 range includes sizes from 15 mm – Rp 1/2" to 54 mm – Rp 2".

Frequently asked questions
What can be connected using the IVAR.IVN462 22 mm – Rp 3/4" sleeve?
An external-threaded valve or fitting can be screwed into the internal Rp 3/4" thread, while the other end is crimped onto a 22 mm stainless steel tube. The sleeve is intended, for example, for closed heating and cooling systems.
What should be used to seal the threaded connection?
The stainless steel crimping system manual recommends sealing materials without chlorides – for example, chloride-free Teflon tape or hemp with a chloride-free sealing compound.
How can I recognize an uncrimped joint?
The broken LBP O-ring will release liquid during a pressure test until the joint is crimped, and the orange stripe signals crimping. Crimping is done using jaws with contour M.
Is the sleeve suitable for potable water?
No, the sleeve is marked with a symbol indicating it is not suitable for potable water. It is used in closed heating and cooling circuits, solar systems, for compressed air or technical gases.
