Press pipe end cap IVAR.IVN450 – stainless steel AISI 304, 88.9 mm
Code: IVN450.89Product detailed description
The IVAR.IVN450 end cap in size 88.9 mm closes the end of a stainless steel pipeline. It has a single press socket that is pushed onto pipe of the same diameter and pressed with a press tool – no threading and no welding. The fitting is not reduced.
The material is stainless steel 1.4301 (AISI 304) and the joint is sealed by an EPDM O-ring. The cap is marked with the AISI 304 logo, the size, a traceability code and a symbol showing it is not suitable for drinking water.
In size 88.9 mm, the cap is supplied without an LBP O-ring and without a coloured press indicator – these are only available on diameters from 15 to 54 mm. Check the joint visually after pressing; according to the installation manual, pressing is clearly visible on large diameters.
Applications
- closed heating and cooling systems
- solar systems
- compressed air and vacuum systems
- inert and technical gases
- technical and process fluids, industrial applications
- waste water and rainwater
The circuit may contain antifreeze at a maximum concentration of 50 %. The end cap is not intended for drinking water installations.
Installation and pressing
Pressing is done with the M profile. For the 88.9 mm diameter, press chains with at least three segments and a suitable adapter are required – the manufacturer does not accept standard one-piece jaws in this size. The V profile is excluded.
For large diameters, the manufacturer recommends fixing the pipes and fitting in installation vices before pressing so that the joint is perfectly aligned.
Cut the pipe end square, deburr it inside and out and mark the insertion depth with a marker. Before pushing the cap on, check the position of the O-ring; if necessary, moisten it with water only – oils, greases and lubricants must not be used. Follow the system installation manual and flush the circuit before commissioning; for treating heating water, the manufacturer recommends GEL.LONG LIFE 100.

Frequently asked questions
What is the IVAR.IVN450 end cap used for?
It closes the end of a 88.9 mm stainless steel pipeline. It is pushed onto the pipe and pressed in the same way as the other press fittings of the system, without threading.
Is the end cap also suitable for drinking water lines?
No. According to the manufacturer, the AISI 304 stainless steel cap is not suitable for drinking water, which is also indicated by a symbol on the product. It is intended for heating, cooling, solar circuits, compressed air and technical gases or fluids.
Which press jaws do I need for the 88.9 mm size?
M-profile press chains with at least three segments, usually with an adapter. The manufacturer does not accept one-piece jaws from 42 mm upwards, and the V profile is prohibited.
Does the 88.9 mm cap have a press indicator or LBP O-ring?
No, both are only supplied on sizes from 15 to 54 mm. On 88.9 mm, pressing must be checked visually.
