Yellow Jacket 4-Valve Manifold Gauge Set

The Yellow Jacket 49973 is a four-valve mechanical manifold gauge set built for HVAC technicians servicing R-22 and R-410A systems. Forged aluminium alloy construction houses liquid-filled gauges rated for 0 to 800 psig pressure and 30 in Hg to 350 psi vacuum. Accuracy is specified at +/- 1.00 percent for reliable diagnostics.

Build integration with 3/8 inch connections

The set connects via 3/8 inch fittings and requires compatible hoses and refrigerant cylinders to complete a service station. Four valves allow simultaneous high-side, low-side, refrigerant tank and vacuum pump hookup, freeing the technician from swapping lines during evacuation, recovery and charge cycles.

Questions about this item

What is the maximum pressure the 4-valve manifold can handle during continuous charging cycles?

The manifold body and gauges are rated for 0 to 800 psig, so sustained high-side charging stays within that limit.

How much heat or vibration does the forged aluminium body transmit to the gauges during all-day use?

The liquid-filled gauges damp vibration and the forged aluminium alloy body dissipates heat, keeping needle drift within the stated ±1.00 percent accuracy.
