Review on Nigo Industrial Co Forged Fitting by Michael Caste

I purchased this 3 way fitting to fit this: https://www.amazon.com/Camco - 59913 -Propane-Hose-Assembly/dp/B007HG7Y7M When I received it, the male heads of this 3-way hose were too small to fit the female heads of a 3/8 inch hose. I know the hose I'm talking about is great because it fits other real 3/8 male heads. I tried this product with a 1/4" female head to see if they accidentally sent me the wrong size, but this time it was too big to fit. I have no idea what size it actually is is, but it is definitely not what is advertised. !
