Review on Orion Motor Tech Refrigerant Puncturing by Jamie Kamoso

A good sensor set for the money! Pretty much everything you need to diagnose and prepare your R134A system including tap, tank adapter and replacement gaskets. Just add a Taylor Precision Products Classic Instant Read Pocket Thermometer and Safety Works 817691 Over Safety Goggles, Clear. R134A is available from Walmart or the Revain website. DuPont 3 cans of R-134a Suva A/C Automotive Refrigerant/Freon R134a (12oz cans). When he first started working with HVAC, my son was able to complete his Chevrolet system in just 30 minutes and enjoy cold air. The gauges seemed accurate, there were no leaks from the hoses or seals. The cost of gauges and 2 bottles of R134A was less than 1/3 of the price he quoted for this service on site. He also received the necessary tool and a new ability. It really helps if someone familiar with automotive HVAC walks you through the first use of the sensors, remembering safety first! He had no problems with high and low fast connections. A tiny grease spot on the inside of the high and low pressure quick release valves allowed for quick and easy opening. I would call them a decent kit for a home mechanic. Would buy again!
