Parker's RGX Series couplings are built to withstand the extreme temperature environment that is required of the self-contained breathing apparatus (SCBA) widely used in the fire rescue community. These quick couplings are directly interchangeable with existing couplings manufactured to the NFPA 1981 requirements.
Parker's Pressure Relief Valve makes it easy to maintain pressure to safely prevent over-pressurization and supports downstream equipment protection on the self-contained breathing apparatus (SCBA). The pressure relief valve is in full compliance with National Fire Protection Association (NFPA) standards.
