Tube cap PRESS IVAR.IVN450 – stainless steel AISI 304, 35 mm
Code: IVN450.35Product detailed description
The cap IVAR.IVN450 for size 35 mm closes the end of a stainless steel pipe. It has a single crimping neck that is slipped onto a pipe of the same diameter and crimped with crimping 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.
The LBP (Leak Before Press) type O-ring is shaped so that an uncrimped connection does not leak during pressure testing and reveals itself. The second indicator is an orange crimping indicator stripe, by which you can easily recognize an uncrimped cap at a glance.
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 mixture with a concentration of up to 50 %. The cap is not intended for potable water systems.
Installation and crimping
Connections are crimped with M-profile jaws. For the 35 mm diameter, the system manual specifies individual (single-piece) jaws; V-profile jaws must not be used for any size.
Cut the pipe end perpendicularly, deburr it from the inside and outside and mark the insertion depth with a marker. Before slipping on the cap, check the position of the O-ring; if necessary, moisten it only with water – oils, greases or lubricants are not used. Follow the system installation instructions and flush the circuit before starting; for the treatment of 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 35 mm. It is slipped onto the pipe and crimped in the same way as other press fittings of the system, without cutting the thread.
Is the cap suitable for potable water systems?
No. The stainless steel AISI 304 cap is not suitable for potable water according to the manufacturer, as indicated by the symbol on the product. It is suitable for heating, cooling, solar circuits and compressed air or technical gas and liquid systems.
Which crimping jaws do I need for the 35 mm size?
Jaws with an M profile; for diameters from 15 to 35 mm, individual jaws are sufficient. The system manual prohibits the use of V-profile jaws.
How can I check if the cap is properly crimped?
The orange crimp indicator stripe and the LBP O-ring help. An uncrimped connection will leak during pressure testing. This way, you can detect an improperly crimped connection before starting the system.
