It is probably more cost effective to use an o-ring sealed adapter to NPT (such as a Swagelok SS-4-SAE-7-4) and an industry standard male NPT transducer, than trying to source a transducer with the o-ring sealed straight thread fitting.</div>

pressure transmitters that<br>will screw in to the high pressure port of a scuba tank. Have had a <br>number of quotes, & it looks like some manufacturers will do a limited<br>run with the non standard 7/16 UNF thread. I am not sure what to <br>specify with regard to thread length. Have measured 3 hp ports &<br>they are around 11.5mm deep. The depth gauge thread that screws <br>in to it is about 8.76mm long & the blank / plug that fits in the port is 7.16mm long.<br>Any transmitter thread length over the port depth will bottom out & not <br>be able to compress the o-ring which is on the pressure transmitter.<br>I was thinking of specifying 10mm but wondered if there was an industry <br>standard length. <br>Am nit picking a bit here but want to get it right, as others may want to<br>order the same product if it works well.<br>Regards Alan<br><br><br>Sent from my iPad<br>_______________________________________________<br>Personal_Submersibles mailing list<br><a href="mailto:Personal_Submersibles@psubs.org" target="_blank" rel="nofollow" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" rel="nofollow">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div> </div></div><div style="margin-top: 2.5em; margin-bottom: 1em; border-bottom-color: rgb(0, 0, 0); border-bottom-width: 1px; border-bottom-style: solid;"></div><pre class="yiv8647327588k9mail"><hr><br>Personal_Submersibles mailing list<br>Personal_Submersibles@psubs.org<br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" rel="nofollow">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br></pre></blockquote></div><div style="margin-top: 2.5em; margin-bottom: 1em; border-bottom-color: rgb(0, 0, 0); border-bottom-width: 1px; border-bottom-style: solid;"></div><pre class="yiv8647327588k9mail" id="yui_3_16_0_ym19_1_1478367957522_4875"><hr><br>Personal_Submersibles mailing list<br>Personal_Submersibles@psubs.org<br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank" rel="nofollow">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br></pre></blockquote></div></div></div><br>_______________________________________________<br>Personal_Submersibles mailing list<br><a href="mailto:Personal_Submersibles@psubs.org" ymailto="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><br><br><br></div> </div> </div> </div></div></body></html>
