Also the regulator fits directly to the tank, so the risk is so minimal. It comes down to our own personal experiences and comfort level. If I have a leak, the alarm will scream before the pressure is an issue. If you are real concerned about over pressures, pick up a small 12 v compressor and plumb it into a small tank to get rid of the pressure. That is one of the benefits of Gamma's internal HP compressor.</span></div><div id="yiv9320978967yui_3_16_0_ym19_1_1494191084121_4975"><span>Hank</span></div> <div class="yiv9320978967qtdSeparateBR"><br clear="none"><br clear="none"></div><div class="yiv9320978967yahoo_quoted" style="display: block;"> <div style="font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font face="Arial" size="2"> On Sunday, May 7, 2017 11:33 AM, hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br clear="none"></font></div> <br clear="none"><br clear="none"> <div class="yiv9320978967y_msg_container"><div id="yiv9320978967"><div><div style="color: rgb(0, 0, 0); font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px; background-color: rgb(255, 255, 255);"><div id="yiv9320978967yui_3_16_0_ym19_1_1494175066843_6205">Hi All,</div><div id="yiv9320978967yui_3_16_0_ym19_1_1494175066843_6205" dir="ltr">I have purchased a few new medical O2 bottles for Elementary 3000. I got a bit worried after the O2 piping and penetrating discussion. I will have internal O2 supply and I admit I had some reservations because the big guys don't do that. Then! this morning I was watching a show on TV about a Saudi Prince flying around in his beautiful two seater glider. Low and behold, there it was, behind the pilot, a O2 bottle. If airplanes can carry O2 tanks inside the plane, why not a submarine? </div><div id="yiv9320978967yui_3_16_0_ym19_1_1494175066843_6205" dir="ltr">Hank</div></div></div></div>_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a href="mailto:Personal_Submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" rel="nofollow" shape="rect">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"><br clear="none"><br clear="none"></div> </div> </div> </div></div></div></blockquote></div><blockquote type="cite"><div><span>_______________________________________________</span><br clear="none"><span>Personal_Submersibles mailing list</span><br clear="none"><span><a href="mailto:Personal_Submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br clear="none"><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" rel="nofollow" shape="rect">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br clear="none"></div></blockquote></div></div><div class="yqt5455013862" id="yqt95028">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a href="mailto:Personal_Submersibles@psubs.org" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" shape="rect">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div><br><br></div> </div> </div> </div></div><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
