Dayton 4PDG7 72 in Blue low side hose

Product Identity

The Dayton 4PDG7 is a 72 in blue low side hose built for HVAC service work. It connects to refrigerant manifold gauge sets with a 1/4 in female fitting at a 30 degree angle. The rubber construction handles a working pressure of 800 psi and a burst pressure of 4,000 psi. Technicians performing refrigerant charging or recovery use this single hose for the low pressure side of the system.

Build Integration

The hose attaches directly to a manifold gauge set, freeing the technician from holding a shorter line during service. Its 72 in length provides reach around engine compartments or equipment cabinets without strain. The auto shut-off connection helps prevent refrigerant loss when disconnecting. No additional adapters are required for standard 1/4 in manifold ports.

Sustained Operation

Under continuous use the rubber hose maintains flexibility while containing pressures up to 800 psi. The 4,000 psi burst rating provides a safety margin during pressure spikes. California Proposition 65 warnings apply because the hose materials contain chemicals identified by the state as causing cancer and reproductive harm. The blue colour identifies the low side circuit at a glance.
