[PSUBS-MAILIST] Pressure Transducer

[Alan James via Personal_Submersibles]

 Just received my 6 pressure transducers from China.These were tailor made for me to fit in to the high pressure portof my first stage regulator; So rather than have high pressure air& oxygen coming through the hull wall, I just have wires.   Unfortunately it looks like they have got it wrong. They have a conicalportion at the base of the male thread that makes it impossible to sealwith an O-ring. I specified 10mm for thread & shank, but the 3mm extra on the conical portion means the flat faces of the pressure transmitter & regulator can't meet. Other than that it looks ideal for potting the wires.   Any suggestions for a fix on this, other than sending them back?I could possibly turn the conical portion down & stack washes under theo-ring. The fit was also a bit sloppy, but so was the original plug that wasin this high pressure port. Not sure if this is normal or not.See attached photos, thanks.Alan
