Review on Robinair 18191A R-134a Refrigerant High Side Service Coupler featuring Red Actuator by John Pound

I bought this coupler and 96" hose from Robinair and I can't use it until I have a 1/4 male to 1/2 male adapter! So I can't even use them until I buy an adapter. I just paid double the money for it than others selling the same thing. Never buy Robin products with your money again! Your customers shouldn't get a penny! I am sending back your hose and coupling! Enough is enough.
