Well I just wanted to make sure before I order, that I am ordering the right sender. I will be buying a NPT to BSPT adapter to screw the sender onto my block.

I am planning to get this VDO gauge:

but it doesn't come with a sender, so this is the one I get for it correct?

It's the only 0-100psi sender. I'm just curious if this is NPT cause it doesn't say "NPT". Also, what does the 27 mean? Sorry for the stupid question, I'm new to this. Thanks guys
