Flange with press socket IVAR.IVN452 76.1 mm, DN 65, stainless steel AISI 304
Code: IVN452.76Product detailed description
The IVAR.IVN452 76.1 mm flange links the stainless steel press system with valves and appliances that have a flanged connection. On one side it has a socket into which the 76.1 mm pipe is inserted and pressed, on the other a DN 65 flange. The socket diameter matches the pipeline, so the fitting is not reduced. It is made of AISI 304 stainless steel (material no. 1.4301) and the pressed joint is sealed by an EPDM O-ring.
DN 65 flange dimensions
- outer diameter D: 185 mm
- bolt circle diameter k: 145 mm
- bolt holes: 4 × Ø 18 mm
- flange thickness H: 18 mm, overall length L: 128 mm
Applications and operating limits
The flange is suitable for closed heating and cooling circuits, solar systems, compressed air and vacuum lines, inert and technical gases, technical and process liquids, and for draining waste water and rainwater. It withstands pressure up to PN 16, vacuum down to -0.8 bar (absolute pressure 0.2 bar), an operating temperature from -20 °C to +85 °C with a maximum of +120 °C, and antifreeze mixtures with a concentration of no more than 50 %. It is not used for drinking water – a symbol on the fitting, marked alongside the AISI 304 logo, the size and the traceability code, indicates this.
Installation
In the 76.1 mm size, neither the LBP O-ring nor the orange indicator strip is supplied (the manufacturer specifies them only for 15 to 54 mm), so the pressing must be checked with particular care. Pressing is done with M-profile press jaws. Installation should be carried out by a qualified professional following the system manufacturer's installation instructions; before commissioning the heating, the manufacturer stresses flushing the entire system and recommends GEL.LONG LIFE 100 for water treatment.
The IVAR.IVN452 range is produced in sizes from 35 to 108 mm.

Frequently asked questions
What does the IVAR.IVN452 76.1 mm flange connect to?
Its socket is pressed onto a 76.1 mm stainless steel pipe and its DN 65 flange is connected to a flanged valve or appliance. It is intended, for example, for closed heating and cooling systems, not for drinking water.
What are the flange dimensions for choosing the mating flange?
The outer diameter is 185 mm, the thickness 18 mm, and the 4 × Ø 18 mm bolt holes lie on a 145 mm bolt circle.
Which tool is used to press the socket?
A press tool with M-profile jaws. First cut the pipe square, deburr it inside and outside, push it in up to the stop and press it at the first attempt – repeated pressing may damage the seal.
Does the 76.1 mm flange have a press indicator?
No, the manufacturer does not specify an LBP O-ring or orange strip for 76.1 mm – they are supplied only for 15 to 54 mm. Therefore check the pressing carefully before the pressure test.

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.
