PRESS coupling with external thread IVAR.IVN481 – stainless steel AISI 304, 42 mm – R6/4"
Code: IVN481.4216Product detailed description
IVAR.IVN481 42 mm – R6/4" (code IVN481.4216) is a stainless steel AISI 304 (1.4301) transition piece with two different ends: a pressing collar for a tube with an outer diameter of 42 mm and an external thread R6/4". 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 transition piece does not reduce the pipe dimension.
For which pipe 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 transition piece is not suitable for potable water. You will find the AISI 304 logo, dimensions, traceability code and a symbol on the body indicating its unsuitability for potable water.
Pressing collar 42 mm
For a diameter of 42 mm, you need tools with medium force (up to 40 kN) and chain pliers with an M profile with at least three segments, usually with a transition adapter; single-piece pliers are not accepted by the manufacturer for this size. V-profile pliers are prohibited for all diameters. An unpressed connection is indicated by an orange stripe on the collar and an LBP (Leak Before Press) sealing O-ring with a broken profile, through which liquid leaks during pressure testing until the connection is pressed.
Threaded side R6/4"
Seal the thread only with material free of chlorides – PTFE tape without chlorides, hemp with sealing paste without chlorides or sealing tape without chlorides, otherwise local corrosion of stainless steel may occur. 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 of at least 50 mm in length between them.
Technical data
- maximum operating pressure PN 16, vacuum down 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 transition piece suitable for potable water distribution?
No. Stainless steel AISI 304 fittings of this range are not intended for potable water, which is also indicated by a symbol on their body. They belong to closed heating and cooling circuits, solar systems or compressed air and technical gas distribution systems.
What pressing tools do I need for a 42 mm collar?
Tools with medium force up to 40 kN and chain pliers with an M profile with at least three segments, usually with an adapter. Single-piece pliers are not accepted by the manufacturer for this diameter.
What to use to seal the external thread R6/4"?
Use only sealing materials free of chlorides – PTFE tape, hemp with paste or sealing tape in a non-chloride finish. Chlorides from the sealing can locally damage stainless steel.
How to find out that the connection 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 connection to leak during pressure testing. You can detect a faulty connection before commissioning.

IVAR designs, develops and manufactures highly energy-efficient heating and plumbing systems. We have over 10,000 catalogue items - mass-produced products and unique items - in addition to customised systems and combinations of complex products. And it’s all “Made in Italy”.
Vision
To make life easier for our clients, our clients' customers and our employees, thanks to our ability to be constantly innovative.
Mission
To design and manufacture advanced hydronic solutions that reduce installation complexity and energy consumption.
“Made in Italy” adds value
IVAR has been producing heating and plumbing system components since 1985: valves for heating bodies, direct heat metering modules, heat cost allocators, pipes and fittings, substations for heating systems, distribution manifolds, radiant panel systems, and components for solar and geothermal systems. And it’s all “Made in Italy”.
Over 200 people are employed at our manufacturing facilities in Prevalle (in northern Italy’s Brescia province). The site has been designed to streamline our many production and operational stages.
The Italian headquarters also acts as a hub for the wider IVAR Group, set up with the goal of distributing products beyond Italy’s borders. The group now has 11 branches, in Australia, Belgium, China, Germany, the United Kingdom, the Czech Republic, Romania, Slovakia, Spain, the United States and Tunisia.
Know How
Research, development and numerous laboratory tests guarantee that our clients’ requests can be translated into new high-efficiency products.
The stages required for production take place internally, beginning with hot forming, which is carried out at our subsidiary Valmon Stampati. Our continuous implementation of projects under the Industry 4.0 initiative also allows us to take full advantage of new releases in technology and IT to improve our manufacturing efficiency.
As a company, IVAR is constantly evolving. Every day, we invest in strengthening our products, in improving our production processes and in attaining new patents and certifications.
