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.




Proven Reliability

The RLS Press Fitting connection process results in a repeatable and reliable mechanical joint every time – as well as a perfectly clean joint inside and out. RLS fittings have a proven track record of reliability, with more than five years of field use and millions of fittings installed worldwide. RLS Press Fittings were specifically designed and engineered for use in high-pressure HVAC and refrigeration systems. They are fully registered and listed to UL207 for pressures up to 700 PSI.
