🔧 CPS Products QC14SET: Effortless R-12 to R-134A Conversion with this High-Performing Coupler Set Review

I bought these to replace the fittings on my Mastercool Professional gauge set, the original fittings lasted 2 years before they started leaking, their quality is amazing , good fit as long as nothing leaks . Very satisfied

Had an old set of gauges and an R12 pump, only needed minor service on the new R134a system. It was cheaper than buying another set of sensors. Arrived on time, well packaged and makes a very high quality impression. I've only used them once so I can't comment on durability; but happy so far.

I bought this connection kit for use at work fixing systems on large coaches that run on a 33lb R134a filling station. The quality of these connectors is top notch, I use them almost every day and they work great. The price is great compared to other clutch kits. The only complaint I have is that Amazon shows a set of chrome connectors, but what I actually received was a brass colored set. Other than that, this is a great kit that I would recommend to anyone involved in car air conditioning…
