Oil pressure sensor seal

[barefoot]

I'm about to replace my oil pressure sensor. How is it supposed to seal? (Should there be a gasket? O-ring? Just the threads themselves?)

I do not see a seal associated with the oil pressure sender.

Is the seal built in like on the oil filter?

The " seal " occurs due to Pipe Taper JIS threads

as the cone gets bigger it seals itself

to be clear , the OIL Sender has the Tapered Brass Threads

Agreed. No seal. Also don’t use Teflon. It needs to ground through contact between the threads.
