Manifold Gauge Kit for HVAC Service

This Dayton 4PDG1 set provides a two-valve brass manifold with three 72 in hoses for charging and diagnosing air-conditioning and refrigeration systems. It covers R-22, R-407C, R-410A and R-404A refrigerants, making it suitable for residential and light-commercial service work. Technicians who need a ready-to-use kit for pressure testing and evacuation will find the included hook and blind ports convenient for storage between jobs. Buyers who require four-valve manifolds or digital readouts should look elsewhere.

Brass Construction With Dry Gauges

The manifold body and piston-style valves are brass, while the 3 1/8 in high-side and low-side gauges are dry types rated 0 to 800 psi and 30 in Hg to 600 psi. Brass resists corrosion from common refrigerants and the dry gauges eliminate fluid leakage risk during transport. The 1/4 in SAE female hose ends thread directly onto standard service ports without adapters. Users who prefer liquid-filled gauges or need a different pressure range will not be served by this kit.

Sustained Use on Refrigerant Circuits

Under continuous charging or recovery the piston valves maintain consistent flow control and the 72 in hoses give enough reach to keep the manifold clear of hot components. Dry gauges retain calibration during long sessions because there is no fill fluid to expand with temperature. Blind ports on the manifold body let you park the hoses safely when switching cylinders or pausing work. Technicians who need higher working pressures or automatic shut-off valves will need a different manifold.

Questions about this item

How do I connect the 72 in hoses to the 1/4 in SAE ports without cross-threading the brass fittings?

Thread each hose onto the manifold ports by hand until the brass seats firmly, then tighten a quarter-turn with a wrench; the piston-style valves seal when fully seated, so over-tightening damages the threads and causes leaks.

When should I replace the three 72 in hoses and the two dry gauges on this manifold set?

Replace hoses if they show cracks, oil residue, or fail to hold 800 psi on the high side; replace gauges when the needle no longer returns to 30 in Hg vacuum or reads above 600 psi inaccurately during recovery.

What pressure limit will I hit first when running R-410A continuously on a hot day with this set?

The high-side gauge stops at 800 psi, so sustained R-410A pressures above that mark will exceed the gauge range before the hoses or brass manifold reach their rated limits.
