<br>Subject: [PSUBS-MAILIST] strain relief fittings
<br><br><div dir="ltr">As mentioned before, I goofed up and welded 7 ss female threaded thru hull fittings in for the Sealcon strain relief fittings before checking that they weren't rated for more than 10 bar which has an IP rating of 68.<div>Since I have a bunch of these already, I plan on using them on the inside as a backup and going with the Blue Globe as recommended by some on this forum because they will take the 300 psi that my sub will see. </div><div>Since Blue Globe is metric, I will need to machine some short ss stubs with the proper metric threads and weld them onto the outsides of my NPT thru hulls so I can take the proper rated fittings.</div><div> I have 4 cables that will have to pass through, 2 @ 4.11 mm, 1 @ 4.87 mm and three @ 5 mm. Can someone recommend who to call to get these sizes in a Blue Globe here in the U.S? </div><div>Thanks </div><div><br></div><div>Rick</div><div> </div></div>
