RLS LLC designed, engineered and developed the first press-to-connect fittings for the HVAC and refrigeration industries. After years of research and development, we introduced our fittings to the market in 2015. Over the years, we continued to expand our product line, regularly introducing new items and new sizes to meet customer needs.
Today, there are millions of RLS fittings installed worldwide, and the original, patented, proven RLS product line remains the only line of refrigerant press fittings in the world to be UL Listed to 700 psi.

RLS Press Fittings let you make a permanent and reliable mechanical connection in just 10 seconds, without the need for brazing. That means significant time and cost savings. In fact, eliminating the brazing step means installation goes up to 60% faster!
Tube ends are prepped in nearly the same way as brazing, but the press tool does all the connection work for you in just seconds. You not only eliminate the time-consuming brazing process, but also the time and effort of hauling heavy brazing equipment from job to job.
