When Ritchie Engineering Co., Inc. began over fifty years ago, it delivered only one product line, top-of-the-line YELLOW JACKET charging hoses. Today, YELLOW JACKET is the leading line of hoses and our product lines have expanded to include not just quality HVAC/R products, but also unparalleled automotive A/C tools.

When Jack Ritchie invented the YELLOW JACKET charging hose, he had one goal…to set the standard by which all other hoses will be measured. That same standard holds true at YELLOW JACKET today. Whether its hoses, gauges, or test and charging manifolds, YELLOW JACKET consistently provides the tools leading refrigeration professionals rely on over every other brand.    

And Ritchie Engineering is expanding its YELLOW JACKET product offerings to meet the needs of the HVAC/R and automobile A/C industries. RST, a leading recovery systems manufacturer, and Corrosion Consultants, a UV lights and dyes manufacturer, joined the YELLOW JACKET team, and the company is continuing to expand its lines, including new electronic products.  

With so many offerings that match their developing needs, it's no wonder that YELLOW JACKET is the first choice of leading HVAC/R and automotive A/C professionals. The advantages of YELLOW JACKET are remarkable.
