This adapter worked perfectly. Had to use an adapter to go for npt to -4an but other then that it’s great. Time will tell though if it stays working as it should.

Runs both mechanical and electrical oil pump gauges.

This is a well made product and will allow one to keep the stock oil pressure switch while adding a separate gauge. The dimensions noted are accurate, I had hoped it would fit (hard to measure on my car) but unfortunately it was just a bit too long (too much work to modify). For informational purposes I was trying to use this on a 2002 Saab 9-5 (2.3T).

Fits perfectly

Perfect for use.. really good quality

Part is made really well, all the threading is done nicely and it fits the BSP and NPT threads as you would expect. As a note for others, does not work in my application for a 2011 Subaru STI for adding an oil pressure port, the adapter is too tall and hits the alternator.

1/8 BSPT to 1/8 BSPT, 1/8 NPT adapter.Good design. 1/8" BNPT on each end fit well. 1/8" NPT on side could be tapped a bit more deep/wide. My oil pressure fitting turned in 1-1/4 turns. Correct application of thread sealant is needed, of course. Next day delivery!

This was a very good machined peice. Treads worked well and there wasn't any metal shavings or anything on it. I used this for my aftermarket oil pressure gauge for the OEM sending unit.

Tried to use the 1/8 npt threaded hole , didnt seem to work. Ruined the threads on my aftermarket oil pressure sensor. Now I have to replace my sensor because this part wasnt machined properly.
