To date I have purchased:
Acuity oil cube---------$40
Adjustable 1/8" bspt die $45
Die handle--------------$10
several 1/8 npt brass fittings about $30
So I'm about to cut the threads down on the Acuity oil cube today and I'm interlocking the threads side by side counting the threads on each when it suddenly hits me, "what if the threads on the switch are in fact 1/8 npt and not bspt?" Nothing says it has to be BSPT...the BSPT fitting doesn't go in the hole any better than the npt fittings I have tried.
I took this picture as a "before" shot and I noticed something that had escaped me up until now. The oil cube threads are not shaped like the switch threads. Even though the two mesh together, I see they don't interlock as well as the oil cube threads do with an NPT fitting. The switch threads are sharp and the oil cube threads are rounded. I went and bought the fitting and the horrendously overpriced die for nothing. Now I gotta buy a sensor adapter that has a 1/8 NPT male and a die to cut IT down! another $50. I don't even know if an adjustable die will close enough to get the threads to the proper diameter to go in the hole.
When I get this done, I hope it saves someone a lot of time and money. It sure is costing me. You'd think someone would have posted more info about this somewhere.
