Paul Conner,

Are you trying to thread this into your block somewhere? In that case, you should know that the threads on the Mazda are not NPT. They are BSPT (British Standard Pipe Thread). They look similar to NPT and an NPT sensor will get partly into the hole but will really be misthreaded. It would be a shame if a whole group of rotary aviation enthusiasts screwed the wrong thread into their blocks, creating metal shavings or worse yet, having a sensor that is hanging on by a couple threads as they crank up the pressure on their engine during takeoff.

Your post specifically references an oil temp sensor. I don't have specific data on oil temp but here's a source that specifically references the oil pressure bung:

Summit Racing (www.summitracing.com) sells the AutoMeter adapter as part number ATM 2269 for--gulp--$10.99.

Hi, fellow rotary enthusiasts....I am trying to find out if anyone has
located, or is using, an oil temp sensor that is a male pipe plug thread,
ie....1/4 NPT or 3/8 NPT.  That would be the simplest installation for me.
Any and all suggestions and/or sources would be much appreciated.  I have
run my engine for approximate 10 minute intervals, and the water temp has
been fine, but don't know about oil temp yet, as I need this sensor.  Thanks
in advance for all replies.  Paul Conner, 13b powered SQ2000 canard
