90° Elbow with External Thread IVAR.IVN431 – Stainless Steel AISI 304, 15 mm x R1/2"
Code: IVN431.1512Product detailed description
The elbow IVAR.IVN431 – 15 mm x R1/2" from the IVAR system made of stainless steel AISI 304 (1.4301) has a crimping collar with an EPDM O-ring for a 15 mm tube on one side, and an external thread R1/2" on the other. It connects a pipe to a heating valve or fitting with an internal thread and simultaneously changes the direction by 90°. It can withstand a pressure up to PN 16 and a temperature range from -20 °C to +120 °C.
Application
Closed heating and cooling circuits, solar systems, compressed air and vacuum lines, inert and technical gases, technical and operational liquids, industrial applications, waste and rainwater. The fitting is not suitable for potable water – this is also indicated by a symbol on its body.
Installation
Cut the tube perpendicularly to the axis using a cutter or fine-toothed file (not a grinding wheel or flame), deburr it inside and outside, and insert it into the collar until it reaches the stop; mark the insertion depth with a marker. Seal the thread with a material free of chlorides, e.g., PTFE tape or hemp with chloride-free sealing paste. Use pliers with an M-profile for crimping, for the 15 mm size use individual pliers. The joint is crimped only once – repeated crimping may damage the sealing.
The orange stripe tears during crimping, so you can easily recognize an uncrimped joint at a glance. The LBP (Leak Before Press) O-ring also allows an uncrimped joint to leak during pressure testing.
Before putting the system into operation, flush the entire circuit and follow the manufacturer's installation instructions. If the valve has an external thread, use type IVAR.IVN430 with an internal thread Rp1/2".

Frequently asked questions
What is the IVAR.IVN431 15 mm x R1/2" elbow used for?
It connects a 15 mm stainless steel crimped pipe to a heating valve or fitting with an internal 1/2" thread and simultaneously changes the direction of the line by 90°.
What should be used to seal the R1/2" thread on the stainless steel elbow?
The installation instructions recommend sealing materials free of chlorides – PTFE tape without chlorides, hemp with sealing paste without chlorides, or sealing tape without chlorides. Chlorides increase the risk of corrosion of stainless steel.
Can the IVAR.IVN431 fitting be used for potable water?
No. The stainless steel system AISI 304 is not intended for potable water by the manufacturer, which is also indicated by a symbol on the fitting body. It is intended for heating, cooling, solar systems, and technical media distribution.
What crimping pliers are needed for the 15 mm size?
Pliers with an M-profile. According to the manufacturer's instructions, individual pliers are used for diameters from 15 to 35 mm.
