The 35-751 First Stage Hose Assembly is included with new Posi3 USB units. The 35-751 is a 3-foot long hose with identical Foster quick disconnect fittings on each end. A model-specific adapter is required to connect the first stage manifold to the breathing apparatus. The adapter must be obtained from the manufacturer of the breathing apparatus, and is typically sold in a kit that also includes the brand-specific software.
