The RPB breathing air hose carries clean, Grade D breathing air from your Radex filter to your RPB Nova 3 or other RPB supplied-air respirator. Unlike ordinary compressed-air hose, which can give off hydrocarbon vapors, it is made specifically for breathing air. It comes in 25, 50 and 100 ft lengths, with 3/8″ ID and RPB quick-connect fittings on both ends.
Approved for use with RPB supplied air respirators and required by NIOSH to complete a compliant respirator assembly, RPB Breathing Airlines help ensure worker safety, regulatory compliance, and uninterrupted productivity. Available with industry-standard quick-connect couplings, as well as RPB RZ fittings that exclusively mate with RZ couplers, these airlines prevent improper connections and guarantee a secure link to the approved breathing air source.
