ISO Flares Replacement

1. Obtain the recommended tubing and steel fitting nuts of correct size. (Outside diameter of the tubing is used to specify size.)
2. Cut the tubing to length. You can determine the length needed by measuring the old pipe using a string and adding 3.2 mm (1/8 inch) for each Isolation Valve (ISO) flare.
3. Install the fittings on the tubing before starting flare.
4. Chamfer the inside and the outside diameter of tubing with the debarring tool. Then flare the tubing ends using an ISO flaring tool, such as J 29803-A ISO Flaring Kit. Follow the instructions included with the tool.
5. Carefully bend the tubing to match the old pipe. Clearance of 19 mm (3/4 inch) must be maintained between the pipe and all moving or vibrating parts.
