It was either a plumbing repair fitting or a liquid tight electrical fitting. The other end was threaded for a regular barb fitting to attach the tubing. Any way, it was a clean looking set up and should not be hard to find.</span></div><div id="yui_3_16_0_ym19_1_1492123844029_2791" dir="ltr"><span><br></span></div><div id="yui_3_16_0_ym19_1_1492123844029_2793" dir="ltr"><span id="yui_3_16_0_ym19_1_1492123844029_2792">Note- the next item in the set up was a water strainer used as an electrical junction box- very helpful to have as a place to disconnect the motor for service.</span></div><div id="yui_3_16_0_ym19_1_1492123844029_2794" dir="ltr"><span><br></span></div><div id="yui_3_16_0_ym19_1_1492123844029_2801" dir="ltr"><span>Greg C</span></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1492123844029_2766"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1492123844029_2765" style="display: block;"> <div id="yui_3_16_0_ym19_1_1492123844029_2764" style="font-family: verdana, helvetica, sans-serif; font-size: 13px;"> <div id="yui_3_16_0_ym19_1_1492123844029_2763" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_ym19_1_1492123844029_2762" dir="ltr"> <font id="yui_3_16_0_ym19_1_1492123844029_2761" face="Arial" size="2"> <hr size="1" id="yui_3_16_0_ym19_1_1492123844029_2814"> <b><span style="font-weight: bold;">From:</span></b> Jon Wallace via Personal_Submersibles <personal_submersibles@psubs.org><br> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br> <b><span style="font-weight: bold;">Sent:</span></b> Thursday, April 13, 2017 3:18 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [PSUBS-MAILIST] Oil Compensator<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1492123844029_2817"><br><div id="yiv3922353280"><div id="yui_3_16_0_ym19_1_1492123844029_2816"><div id="yui_3_16_0_ym19_1_1492123844029_2815" style="color: rgb(0, 0, 0); font-family: times new roman, new york, times, serif; font-size: 16px; background-color: rgb(255, 255, 255);"><div id="yiv3922353280yui_3_16_0_ym19_1_1492110421353_8633"><span></span></div> <div class="yiv3922353280qtdSeparateBR" id="yiv3922353280yui_3_16_0_ym19_1_1492110421353_8754" dir="ltr">What are you psubbers with MK101 motors using for air compensation tubing? The O.D. of the MK101 shaft knob is 1.385 inches or 35.179mm. I'm having a hard time finding a supplier of 1.375 inch I.D. hose which should be able to fit over the shaft knob after heating and some persuation, should I decide on an air compensation for the motors. In lieu of finding some inexpensive tubing of this size, are there any off-the-shelf nipples of the correct thread that be threaded into the shaft knob to reduce the hose size?</div><div class="yiv3922353280qtdSeparateBR" id="yiv3922353280yui_3_16_0_ym19_1_1492110421353_8754" dir="ltr"><br></div><div class="yiv3922353280qtdSeparateBR" id="yiv3922353280yui_3_16_0_ym19_1_1492110421353_8754" dir="ltr">Jon</div><div class="yiv3922353280qtdSeparateBR" id="yiv3922353280yui_3_16_0_ym19_1_1492110421353_8754" dir="ltr"><br></div></div></div></div>_______________________________________________<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>
