i think you guys are overthinking this. the isolation valves and test jigs were just made up of fittings, brake tubing, common gauges and ball valves. i will bet every one of us that has them they are different because we made them out of what we had plus any parts we needed to add. plus it will depend if you are doing 1/4 inch lines or 3/8 inch lines. you need to make up one that fits your need.
