PRESS IVAR.IVN450 Pipe Cap – AISI 304 stainless steel, 88.9 mm
Code: IVN450.89Product detailed description
The cap IVAR.IVN450 for size 88.9 mm closes the end of a stainless steel pipe. It has a single pressing collar that is slipped onto a pipe of the same diameter and pressed with pressing tools – without cutting threads and without welding. The fitting is not reduced.
The material is stainless steel 1.4301 (AISI 304), the connection is sealed with an EPDM O-ring. The cap is marked with the logo AISI 304, the size, the traceability code, and the symbol indicating unsuitability for potable water.
In size 88.9 mm, the cap is delivered without the LBP O-ring and without a color indicator for pressing – these are included only for diameters from 15 to 54 mm. After pressing, therefore, visually check the connection; for large diameters, pressing is clearly visible according to the installation instructions.
Application
- closed heating and cooling systems
- solar systems
- compressed air and vacuum systems
- inert and technical gases
- technical and operational liquids, industrial applications
- sewage and rainwater
The circuit may contain antifreeze mixtures with a concentration of up to 50 %. The cap is not intended for potable water supply.
Installation and pressing
Connections are pressed with contour M. For a diameter of 88.9 mm, chain jaws with at least three segments and a suitable adapter are required – the manufacturer does not accept standard single-piece jaws for this size. Profile V is excluded.
For large diameters, the manufacturer recommends clamping the pipe and fitting into installation jigs before pressing to ensure the connection is properly aligned.
Cut the pipe end perpendicularly, deburr it on the inside and outside, and mark the insertion depth with a marker. Before sliding on, check the position of the O-ring; if necessary, moisten it with water only – oils, greases, or lubricants are not used. Follow the system installation instructions and flush the circuit before starting; for treating heating water, the manufacturer recommends GEL.LONG LIFE 100.

Frequently asked questions
What is the IVAR.IVN450 cap used for?
It closes the end of a stainless steel pipe with a diameter of 88.9 mm. It is slipped onto the pipe and pressed like other press fittings in the system, without cutting threads.
Is the cap suitable for potable water supply?
No. The cap made of stainless steel AISI 304 is not suitable for potable water according to the manufacturer, as indicated by the symbol on the product. It is intended for heating, cooling, solar circuits, and compressed air or technical gas and liquid systems.
What pressing jaws do I need for size 88.9 mm?
Chain jaws with contour M and at least three segments, usually with a transition adapter. The manufacturer does not accept single-piece jaws for diameters from 42 mm and above, and profile V is prohibited.
Does the 88.9 mm cap have a pressing indicator or LBP O-ring?
No, both are included only for sizes from 15 to 54 mm. For 88.9 mm, pressing must be visually checked.
