Rapid Locking Systems
Rapid Locking System
RLS press fittings
were specifically designed and engineered to join copper tubes in high-pressure
HVAC and refrigeration systems.
Our patented RLS press fittings are fully
registered and listed to UL207 for pressures up to 700 PSI. These
first-of-their-kind fittings connect quickly and easily using an RLS-approved
press tool and jaws, replacing the time-consuming practice of manually brazing
The pressing procedure is similar to the one used with water press
fittings. RLS press fittings, however, were developed to withstand the high
pressures found in HVAC/R systems.
