Anyone here familiar with the various threaded fitting types used on propane tanks? I have a number of tanks I use on my forklift, but I'd like to use them on my turkey frier instead of buying "blue rhino" tanks which cost more to refill than hitting the U-Haul. Unfortunately the couplers don't match up. Forklift coupler is brass, seems has a straight internal stub with rubber rings inside the female on the tank. On the turkey frier it has the plastic knob and the inner brass with the tapered nose. Are there standard names so I can search for adapters or hose couplers?
