45° Bend IVAR.IVN422 – press x press, stainless steel AISI 304, 18 mm
Code: IVN422.18Product detailed description
The IVAR.IVN422 – 18 mm bend from the IVAR system in AISI 304 stainless steel (1.4301) has a press socket with an EPDM O-ring at both ends. It joins two 18 mm pipes at 45° without changing size. It handles pressures up to PN 16 and temperatures from -20 °C to +120 °C.
Applications
Closed heating and cooling circuits, solar systems, compressed air and vacuum lines, inert and technical gases, technical and process liquids, industrial applications, waste water and rainwater. Not for drinking water – a symbol on the fitting also indicates this.
Installation
Cut the pipe square with a pipe cutter or fine-toothed saw (no angle grinder or flame), deburr it inside and out and push it in up to the stop; mark the insertion depth with a marker. Press with M-profile jaws; for size 18 mm, standard jaws. Each joint is pressed only once – pressing again may damage the seal.
The orange strip tears during pressing, so an unpressed joint is visible at a glance. In addition, the LBP O-ring (Leak Before Press) lets medium escape from an unpressed joint during the pressure test.
Flush the entire circuit before commissioning and follow the system manufacturer's installation instructions. If you need a spigot end on one side, choose type IVAR.IVN423 in the same size.

Frequently asked questions
Can the IVAR.IVN422 fitting be used for drinking water?
No. The manufacturer does not intend the AISI 304 stainless system for drinking water, which is also indicated by a symbol on the fitting body. It is designed for heating, cooling, solar systems and lines for technical media.
Which press jaws do I need for the 18 mm size?
M-profile jaws. For diameters from 15 to 35 mm the manufacturer's instructions specify standard jaws.
How do I spot a joint I forgot to press?
On an unpressed fitting the orange strip stays intact; it tears during pressing. In addition, the LBP O-ring lets the medium through during the pressure test, so the mistake shows up before commissioning.
Can antifreeze be used in a circuit with this bend?
Yes, the manufacturer allows antifreeze at a concentration of no more than 50%. The operating temperature may range from -20 °C to +120 °C.

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.
