Use this aluminum boost leak tester tube to check your system for leaks. The tube is 3" and has the necessary bead formed on the end so it will not blow off during tests. The other end has a 1/4" NPT bung for you to attach all of your necessary air hoses, gauges and fittings.
For additional cost, we can supply all the fittings, valve, and gauge built in to the handle like you would use when inflating a tire. The actual inflator may differ from the picture as we will supply a proper piece that will provide years of hassle free use.
