Fluidyne Radiator - Help!!! Pluging up Temp. Sensor Hole

Guest

Hello! Merry Christmas Eve everyone, and a happy holidays.

I have recieved my Fluidyne radiator, but I am not using a tempature sensor unit on the radiator using those two threaded holes they have. What can I use to plug it up?

I called the company I ordered it from and they don't know the exact size, but they saiad it's metric.

7/8 was the closest in standard size, and the cloest in metric to that is M22, but all I can find online like at www.mcmaster.com was M22 with a pitch thread of 2.5mm which is too course, I believe the hole needs a finer pitch of 1.5mm and I can't find any of this.

Is there an auto plug that'd designed to plug up this radiator? I'm sure someone on this forum uses a Fluidyne radiator and don' thave 2 sensors on theirs. Can you tell me what you used to plug it up?

Thanks! I really appreicate any help i can get!
