i have a phantom series mechanical oil pressure gauge and electrical water temp gauge. i was wondering that size the threads were for the oil pressure sensor and water temp. sensor. i think i need an adapter because the threads on the autometer sensors are strandard. has anyone put in these gauges in their integra? anyone know where i can find an adapter?
thanks,
Jon

 

1/8" NPT is what they use.

1/8" BSPT is what's threaded in your engine block for the oil pressure switch. z10eng.com sells a BSPT to NPT adaptor. However, you can get away with threading the NPT into the block, you just have to be careful. If you think it's not a good idea for you do so, then get the adaptor.

 

I have heard stories. I recomend getting the adapter.

 

and the inner threads are all the same for all auto meter lines?

thanks a lot guys

 

sorry to bring this up again. DC2, you said i need a 1/8 BSPT to 1/8 NPT, correct? i emailed autometer and they replied back saying i need a 1/8 NPT to 1/8 BSPT (part #2269) now i am all confused.
how do the BSPTs and the NPTs compare? does one have slightly larger threads on them? which one?

thanks,
Jon
