Go to "<a href="http://thescubadiversstore.com">thescubadiversstore.com</a>" and then type in the search bar 46335 and it will pull up a bleed part but the one I have does not the have threaded port for a gauge. The guy was really great to work with and good prices as well. This will get you started and when I get to me shop, I'l look up the part number that doesn't have the gauge port and get that to ya.</div><div>Rick</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 28, 2019 at 6:06 PM Alan via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi,<br>
Just wondering if people use / have an external valve to purge air / O2 from the <br>
system to enable the removal of the first stage yoke from the tank.<br>
With a dive set up you just press the second stage purge valve.<br>
