Tool Releases Hydraulic Pressure
The tool makes use of the following parts: a female ISO hydraulic coupler, a 3/8-in. flange nut, a 3/8 by 2 1/2-in. bolt, a 1/8-in. pipe elbow, and a 2-in. long, 3/8-in. dia. round bar.
To build the tool, Sharpe uses a needle nose pliers to unscrew and remove the internal components from the coupler, leaving an open barrel that will couple onto the hose under pressure. The next step is to weld the flange nut upside down into the coupler’s threaded opening. Sharpe welds the 2-in. long round bar horizontally to the top of the bolt to make a “T”. He inserts the bolt into the nut so it extends down far enough to reach into a coupler. He also drills and taps a hole in the side of the coupler to insert a small pipe elbow.
To use the tool, he connects the coupler to the hose and then gently screws the bolt in until it contacts the ball in the center of the coupler tip to relieve the pressure. The fluid comes out of the pipe elbow and can be collected in a Dixie cup.
“Make sure you don’t screw the bolt down far enough to damage the coupler. You can prevent that by trimming the bolt length,” says Sharpe.
