Robinair(18190A) R-134a Low Side Service Coupler with Blue Actuator

I purchased this item and its companion low-pressure (blue knob) service valve independently since the combined set was overpriced compared to previous same-purchase last year. Waited for sale on these individual high/low valves so that 2 individual purchased combined matched pricing on set from previous purchase. The valves seem solid and have proved to be durable; but due to the nature of these valves they are not guaranteed to remain leak-free indefinitely. For this reason we keep ample supply of valves on-hand to prevent a/c equipment from otherwise falsely flagging an a/c leak on a vehicle. The delivery time was as expected but would have preferred not to have waited so long for price to drop to reasonable levels, so deduct one star only. There are cheaper choices out there, but a/c machines are very sensitive to leaks when hooked up to the vehicle; so minimize the risk of a false flag and get quality Robinair valves and replaced whenever needed.

I have used Robinair products for many years and would not hesitate to buy their equipment.

I bought Robinair thinking it would be a reputable manufacturer, but I should have read the reviews, as the low side coupler leaks badly, like many people's review on this item.

Not impressed with Robinair at all. I thought it was a decent name. This set is one the better sets they sell. Cheap seals, the quick couplers leak alot. (low side). Causing leaks under vacuum, wasting my time chasing ghosts, when it's these crap gauges. Tired of low quality sh*t. wasting my f*cking life! JUNK!!!!!!!!!

I had a hard time trying to connect it to my 2003 Mazda Protege ac connection. I had to use tremendous amount of force to eventually lock it onto the suction connection. Once connected, it sits solidly and did not leak. It was well built. I give 2 stars because of difficulty with connection.
