<div dir="ltr" data-setdir="false">Alan, I have tested my penetrators with no additional glue or silicone. I agree silicone or glue is a good idea but in testing I have discovered that it takes 1,000 psi before air will pass between the wire shield and up the wire. I tested be screwing the penetrator into a pipe. I pressurized the pipe interior with air not water. I then place the pipe in a bucket of water to look for bubbles. Not until 1,000 psi will very minor random air bubbles appear. If the test was reversed with water in the pipe then I suspect it would take much more pressure to push water past. </div><div dir="ltr" data-setdir="false">Hank</div><div><br></div>
