Water pump threaded fitting replacement

Question

I have a Artis products PDS1RV25 water pump. It has male threaded fittings. I would like to buy a fitting and hose section to put on the suction side in order to winterize. I called their tech support and asked what type of fitting I should use (NPT, NPSM, other?) and they had no idea. He just said use a plastic fitting from a home improvement store and it it doesn't go on smoothly try something else.

From the a photo on their web site it seems like it must be some kind of straight threaded fitting that seals with an o-ring or rubber washer.

Should I be looking for 1/2" NPSM fittings?

my pump is easy to reach....I undo the hose from the tank to the pump and then just use a standard sink installation hose.like one of these.screws right on to the pump.. I put the other end in the jug of anti freeze and it works perfectly.
