It's interesting that your Defi gauge is 1/8 BSP; which do you have? I have the Defi BF Advance, and the manual is saying it's 1/8 NPT.
Well, the acronyms used for pipe threads certainly can be confusing. The install manual for my Defi Racer gauge indicated that the threads on the sensor were 1/8 PT ... which is a Japanese Industrial Standard (JIS) designation. After researching the different thread types and designations, I discovered that the 1/8 PT thread was equivalent to and interchangeable with 1/8 BSPT. So, you don't need an adapter if you intend to install the Defi sensor directly into the factory engine port since that port is 1/8 BSPT. In my case, I needed an adapter to fit the sensor into the oil filter sandwich plate since the port on the plate was 1/8 NPT (i.e., I used a 1/8 PT or BSPT male to 1/8 NPT female adapter). Trust this helps!

It's probably NPT if the package says so.
From the Defi web site:

Are you sure your sensor is 1/8 NPT? I goggled the install instructions for the Defi BF Advance gaugesand it appears the sensor thread is 1/8 PT.

You are correct. I'm not sure how my brain added the N to PT. So just to summarize, PT=BSPT and not NPT?

Yes, evidently PT = BSPT. I goggled "What does JIS PT mean" and checked a few of the links and they indicated that PT was equivalent to BSPT.

Raising this thread as I finally had a chance to observe oil pressure for a moment and I'm not sure if I'm worried for no reason or not.

So, I only just checked cold/warm idle and 3k rpm pressures and they were:

Cold startup oil pressure: 7.5bar ~ 108psi
Warm idle oil pressure: 1.6bar ~ 23psi
Warm at 3k rpm: >4bar ~ 58psi

This is with the 25row oil cooler with the thermostatic plate (so it wasn't open at the time of reading), and the pressure sensor is Tee'd of the factory mounting point.

I have replaces galley gaskets last year. This should all be good, right?

Those all seem fine. Maybe a bit lower than typical but they’re in spec.

Nissan calls out >14psi at idle, >42psi at 2k rpm when warm.
