Rapid Locking System Europe operates as a subsidiary of Rapid Locking System USA LLC. RLS LLC is the pioneering force behind the development, design, patenting, and engineering of the world’s first press-to-connect fittings for the HVAC and refrigeration industries. These innovative fittings were introduced to the market in 2015 following years of dedicated research and development.


RLS Press Fittings take the danger of an open flame out of the workplace, creating a safer work environment with no fire hazards. That means there’s no need for hot work permits, fire spotters or fire-related safety equipment. No brazing also means no need to nitrogen purge, and no need to transport gas and other brazing equipment to the job site.

Plus, as the use of flammable refrigerants in the HVAC and refrigeration industries continues to increase, the safety of flame-free RLS Press Fittings will become even more important.

Faster and Easier

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. Just watch this quick video to see how fast and easy it is to make an RLS connection.
