Parallel thread but seems to seal with plenty of PTFE tape.
My flow sensor is now completely dead, was installed last Oct/Nov so not very reliable.

I would set it up like this with an o-ring just as it is intended. This being the pump's male end and the green being the o-ring. PTFE is not harmful, but NEVER use pipe dope on plastic parts. It can weaken and fracture the parts down the road.
The o-ring also acts as a spring to keep the thread under tension so it doesn't vibrate loose.
Go to a small hardware store and hand-fit an o-ring from their selection. Home Depot/Lowe's would not have o-rings by the piece like this.
