<div dir="auto">Hi Steve, I am using 3 alum 80's with standard yoke on the SeaQuestor. Spare orings always available. I chose this over din, just for or the fact that more tanks are sold with the standard yoke, and in the event i need quick replacement tanks, i dont need to look for din valve tanks. The oring issue we had on the gamma, i believe was caused by an improper seating of the whip to the yoke when the tank was replaced prior to the dive. It was only discovered after we were on statation and turning on the air that it became an exciting moment. In my predive checklist, all tank yokes are to be checked by the same person after an oring inspection. And off course spare orings on board the sub and support vessel.<div dir="auto">David</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Feb 20, 2020, 7:54 AM Steve McQueen via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">All, getting ready to buy 2 scuba tanks for my K250.
