Flange with Compression Neck IVAR.IVN452 42 mm, DN 40, Stainless Steel AISI 304
Code: IVN452.42Product detailed description
Flange IVAR.IVN452 42 mm connects the crimping system made of stainless steel with valves and devices that have a flange connection. On one side it has a sleeve into which the 42 mm pipe is inserted and crimped, on the other side it has a DN 40 flange. The sleeve diameter corresponds to the pipe, so the fitting is not reduced. It is made of stainless steel AISI 304 (material 1.4301), and the crimped joint is sealed with an EPDM O-ring.
Flange DN 40 dimensions
- outer diameter D: 150 mm
- hole circle diameter k: 110 mm
- holes for bolts: 4 × Ø 18 mm
- flange thickness H: 16 mm, total length L: 77 mm
Application and operating limits
The flange is suitable for closed heating and cooling circuits, solar systems, compressed air and vacuum distribution, inert and technical gases, technical and operational liquids, and for drainage of waste and rainwater. It can withstand a pressure up to PN 16, a 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 a non-freezing mixture with a concentration of up to 50 %. It is not suitable for drinking water – this is indicated by a symbol on the fitting, together with the AISI 304 logo, dimensions and traceability code.
Installation
The 42 mm sleeve has a patented LBP (Leak Before Press) O-ring with a segmented profile, which during a pressure test reveals an uncrimped joint by a liquid leak, and an orange stripe indicating the crimping. It is crimped using jaws with contour M. Installation should be carried out by a qualified professional following the manufacturer's installation instructions; before starting heating, the manufacturer emphasizes the need to flush the entire system and recommends using the preparation GEL.LONG LIFE 100 for water treatment.
The IVAR.IVN452 range is produced in sizes from 35 to 108 mm.

Frequently asked questions
What is the IVAR.IVN452 42 mm flange connected to?
It is crimped onto a stainless steel pipe of 42 mm and connected via a DN 40 flange to a flanged valve or device. It is intended, for example, for closed heating and cooling systems, not for drinking water.
What dimensions does the flange have for selecting a gasket?
The outer diameter of the flange is 150 mm, the thickness is 16 mm, and the 4 × Ø 18 mm bolt holes lie on a circle with a diameter of 110 mm.
With what tool is the sleeve crimped?
Using a crimping tool with jaws of contour M. Cut the pipe perpendicularly first, deburr the inside and outside, insert it fully and crimp it in one attempt, as repeated crimping may damage the seal.
Can I tell if the sleeve remains uncrimped?
Yes, the LBP O-ring will allow liquid to pass during a pressure test until the joint is crimped, and the orange stripe indicates the crimping status. For the 42 mm size, both features are included.
