90° Press x Press IVAR.IVN420 – stainless steel AISI 304, 18 mm
Code: IVN420.18Product detailed description
The IVAR.IVN420 elbow in size 18 mm bends stainless steel pipe at 90°. Both ends are press fittings (PRESS x PRESS) for the same pipe diameter – the fitting is not reduced. The body is made of stainless steel AISI 304 (1.4301), the connection is sealed with an EPDM O-ring.
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
- sewage and rainwater
Not suitable for potable water systems.
Pressing size 18 mm
The connection is pressed using M-profile jaws; for a diameter of 18 mm, individual jaws are sufficient. An orange stripe on the fitting indicates an unpressed connection, and the LBP (Leak Before Press) O-ring releases liquid during pressure testing until the fitting is pressed – an unpressed connection is immediately visible.
Cut the pipe perpendicularly to the axis, deburr the inside and outside, and mark the insertion depth with a marker. During installation, follow the manufacturer's installation instructions and flush the entire system before putting it into operation.
Operating parameters
Pressure up to PN 16, vacuum down to -0,8 bar (absolute pressure 0,2 bar), temperature -20 °C to +120 °C, antifreeze mixture concentration up to 50 %. Dimensions according to technical drawing: L 45 mm, Z 24 mm.
The same range also includes a 90° elbow with one push-fit end, IVAR.IVN421.

Frequently asked questions
Can the IVAR.IVN420 elbow be used for potable water?
No. According to the manufacturer, fittings made of stainless steel AISI 304 are not suitable for potable water. They are intended for closed heating and cooling circuits, solar systems, and compressed air, technical gas and liquid systems.
Which pressing jaws do I need for size 18 mm?
Jaws with M profile. For diameters from 15 to 35 mm, individual jaws are used according to the installation instructions.
How do I recognize an unpressed connection for size 18 mm?
The fitting has an orange pressing indicator and an LBP O-ring, which releases liquid during pressure testing until the connection is pressed.
Can antifreeze mixture be used in the circuit?
Yes, its concentration can be up to 50 %. Operating temperature is -20 °C to +120 °C at pressure up to PN 16.

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.
