PRESS IVAR.IVN481 adapter with external thread – stainless steel AISI 304, 28 mm – R1"
Code: IVN481.2810Product detailed description
IVAR.IVN481 28 mm – R1" (code IVN481.2810) is a stainless steel AISI 304 (1.4301) elbow with two different ends: a pressing collar for a pipe with an outer diameter of 28 mm and an external thread R1". You can use it wherever a pressed stainless steel pipe continues into a heating fitting or elbow with an internal thread. The pressing collar corresponds to the pipe diameter, so the elbow does not reduce the pipe dimension.
For which systems
- closed heating and cooling circuits, solar systems
- compressed air and vacuum systems
- inert and technical gases, technical and operational liquids
- industrial applications, waste and rainwater
The elbow is not suitable for potable water. You will find the AISI 304 logo, dimensions, traceability code, and a symbol on the body indicating that it is not suitable for potable water.
Pressing collar 28 mm
For this size, even a portable pressing tool with low force (up to 17 kN) is sufficient, which according to the manufacturer's instructions presses approximately up to a diameter of 28 mm, using single-jaw tools with an M profile. V-profile jaws are prohibited for all diameters. An unpressed joint is indicated by an orange stripe on the collar and a sealing O-ring LBP (Leak Before Press) with a broken profile, through which liquid leaks during pressure testing until the joint is properly pressed.
Threaded side R1"
Seal the thread only with materials free of chlorides – PTFE tape without chlorides, hemp with sealing paste without chlorides, or sealing tape without chlorides, as chlorides can cause local corrosion of stainless steel. Stainless steel is compatible with brass, bronze, or copper fittings; if it is to come into direct contact with carbon steel, the manufacturer recommends inserting a colored metal spacer at least 50 mm long between them.
Technical data
- maximum operating pressure PN 16, vacuum up to -0.8 bar (absolute pressure 0.2 bar)
- antifreeze mixture with a concentration of up to 50%
During installation, follow the installation and use instructions for the IVAR pressing system. Before starting, flush the entire heating system – for its treatment, IVAR recommends the preparation GEL.LONG LIFE 100.

Frequently asked questions
Is the IVAR.IVN481 elbow suitable for potable water distribution?
No. Stainless steel AISI 304 elbows of this series are not intended for potable water, which is also indicated by a symbol on their body. They are suitable for closed heating and cooling circuits, solar systems, or compressed air and technical gas distribution.
What pressing tool do I need for the 28 mm collar?
A portable tool with low force up to 17 kN with single-jaw tools with an M profile is sufficient. V-profile jaws must not be used.
What should I use to seal the external R1" thread?
Use only sealing materials free of chlorides – PTFE tape, hemp with paste, or sealing tape in a chloride-free version. Chlorides from the sealing material can locally damage the stainless steel.
How can I tell that the joint is not yet pressed?
There is an orange indicator stripe on the collar, and the LBP O-ring with a broken profile causes the unpressed joint to leak during pressure testing. This way, you can detect an improperly pressed joint before putting the system into operation.
