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

I would give zero stars if possible! When I first used this item, the hose burst. The printing on the hose lists a working pressure of 600psi and a burst pressure of 3,000psi, but the hose ruptured in multiple places when the pressure reached 300psi. I thought Robinair was a good name with quality products but that is no longer the case. Unfortunately I had already passed the 30 day return window before using it for the first time. I think I wasted my money.
