So in this video, I put on the adapter like anyone would til it's snug. pressed down and little air came out after release like i mentioned. the times when the gas was coming out was because i bent the adapter nozzle a little so there was an air gap in the spring part of the adapter itself thus expelling the gas. the propane doesn't actually go through the adapter like it should.

i also noticed for madbull adapters they encase the pin of the propane like shown here
