Dayton 4PDG2 4-Valve Manifold Set

The Dayton 4PDG2 is a four-valve manifold gauge set built for HVAC technicians who service R-12, R-22 and R-502 systems. It includes four 6 ft hoses and aluminium manifold body with piston-style valves for refrigerant control.

Verify refrigerant compatibility

Before ordering, confirm the job requires gauges rated for R-12, R-22 and R-502 refrigerants. Ensure your service hoses and fittings match the manifold ports and that the 6 ft hose length suits the work area layout.

Oil-filled gauges steady the needle under load

The 2 3/4 in high and low-side gauges are oil-filled to damp vibration during extended charging or recovery sessions. The 0 to 500 psi and 30 in Hg to 350 psi scales remain readable when system pressure fluctuates over long periods.

Questions about this item

Does the Dayton 4PDG2 manifold gauge set ship with the four 6 ft hoses attached, or do I need to order hoses separately?

The set includes four 6 ft hoses along with the four-valve manifold, so no separate hose purchase is required.

The specs list R-12, R-22 and R-502 — how do I know which refrigerant scale to use on the gauges?

The 2 3/4 in oil-filled gauges carry scales for R-12, R-22 and R-502; select the scale that matches the refrigerant in the system you are servicing.

What does the 0 to 500 psi and 30 in Hg to 350 psi range mean when I hook this up to a live A/C system?

The low-side gauge reads vacuum down to 30 in Hg and pressure up to 350 psi, while the high-side gauge reads 0 to 500 psi, covering the full operating envelope for R-12, R-22 and R-502 systems.
