The RAPID LOCKING SYSTEM 3011181800111 coupling is designed to join copper tube in high-pressure HVAC and refrigeration systems. These fittings connect quickly using an RLS-approved press tool and jaws, replacing the time-consuming practice of manually brazing joints. RLS Press Fittings are fully registered and listed to UL207 for pressures up to 700 PSI.
RLS press fittings provide higher-quality work completed by fewer people in less time, increasing profit per job.
