But yes, you leave the piston in, if it is double acting and either all of the rod or cut the excess off, I would leave it intact. I can either use water or air, normally I think you would fill with water for safety also to locate a leak in your test part. I use air because the cylinder is safe and rated. If you find a double acting cylinder, you can also remove the piston and just use the piston nut and washer to hold the rod in from pushing out. Then you can use the second port for filling with water while it vents out the opposite port. Then you just need a tee with gauge and valve. You can pressurize it with your scuba tank or a pressure washer. The scuba tanks make the most sense if you fill with water first so you displace all the air. You will need to make a small air chamber to go inside if your testing your penetrators. Just take a pipe threaded at both ends, screw a cap on one end and a fitting at the other that will except your penetrator. This way you have water pushing against the penetrator with air on the opposite side of the penetrator</span>. So long story, but try to find a double acting cylinder, either screw on top or tie rod type with four long bolts is also fine. Easy to do with no welding or machining.</div><div id="yui_3_16_0_1_1447592466784_6559" dir="ltr">Hank</div><div id="yui_3_16_0_1_1447592466784_6559" dir="ltr"><br></div> <br><div
