There are Swagelok and other fittings which will work, but watch your wrench clearances when using multiple adjacent ports. On that note, LP SCUBA ports are either 3/8-24 UNF - 2B (most common) or 1/2-20 UNF - 2B (less common). Be aware that while most HP SCUBA SPG hoses have a pinhole bore in order to reduce the consequences of a HP hose failure, some SCUBA regulators incorporate the pinhole restriction into the regulator itself, which will limit the available flow rate at high pressure. Of course, if your drawing gas off at high pressure anyway, why go through the reg?<br><br>Sean<br><br>Sent from ProtonMail mobile<br><br><br><br>-------- Original Message --------<br>On Mar 11, 2018, 07:12, Jon Wallace via Personal_Submersibles < <a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<o:p></o:p></span></p><p class=MsoNormal style='background:white'><span style='font-size:9.5pt;font-family:"Helvetica","sans-serif";color:black'><o:p> </o:p></span></p></div><div id=yiv8090308004yqt66975><div><div><div><p class=MsoNormal style='background:white'><span style='font-size:9.5pt;color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal style='background:white'><span style='font-size:9.5pt;color:black'>Are there adapters that can change a SCUBA HP hose fitting to NPT?<o:p></o:p></span></p></div><div><p class=MsoNormal style='background:white'><span style='font-size:9.5pt;color:black'><o:p> </o:p></span></p></div><div id="yiv8090308004yui_3_16_0_ym19_1_1520777355398_5939"><p class=MsoNormal style='background:white'><span style='font-size:9.5pt;color:black'>Jon<o:p></o:p></span></p></div><div id="yiv8090308004yui_3_16_0_ym19_1_1520777355398_5940"><p class=MsoNormal style='background:white'><span style='font-size:9.5pt;color:black'><o:p> </o:p></span></p></div></div></div></div></div><div id=yqt72858><p class=MsoNormal style='background:white'><span style='font-size:9.5pt;font-family:"Helvetica","sans-serif";color:black'>_______________________________________________<br>Personal_Submersibles mailing list<br><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><o:p></o:p></span></p></div><p class=MsoNormal style='margin-bottom:12.0pt;background:white'><span style='font-size:9.5pt;font-family:"Helvetica","sans-serif";color:black'><o:p> </o:p></span></p></div></div></div></div></div></div></body></html>
