Don't see why it wouldn't work for this application, as well.

Subject: [PSUBS-MAILIST] Penetrator Air Void Question/Concern<br>
<br>
All, I am running a multi conductor cable (11-12mm OD) for my 12V stern thruster thru an existing 1/2" pipe nipple in the aft head of my K-250.<br>
<br>
I am using a Blueglobe gland fitting (BG 220 VA, rated @ 1,160 psig) on the outboard pressure side of the nipple and a Conax gland (PG5-500-A-N,rated @ 800 psig) for the gland fitting inboard.<br>
<br>
I was originally only going to have interior Conax gland and let the pipe free flood. Then I decided I wanted to have redundancy and keep the pipe interior dry to help prevent corrosion (it is old school (not SS)). <br>
<br>
My question: Is the air void that will exist between the 2 gland fittings a concern? Think empty pipe with both ends capped. I'm thinking not...<br>
<br>
<br>
Thanks,<br>
Steve<br>
