HVAC Valve Core Removal Set

The DNBeffulgent DR-Dreyoo-1170 set provides a six-piece kit for servicing air-conditioning and refrigeration systems. It includes a valve core remover wrench, ratchet wrench, brass adapter, valve core rod, five brass nuts and twenty valve cores. The tools handle refrigerant ports without discharging the charge.

Compatible Refrigerants and Limitations

The brass wrench fits SAE 1/4'' and 5/16'' ports covering R22, R12, R134, R404, R407, R410 and R32 systems. The ratchet wrench offsets both ends by 25 degrees for confined spaces and uses quick-flip steering levers. The kit is not suitable for automotive air-conditioning work.

Build Integration and Workflow

The S2 alloy steel hex bit adapters in 3/16'' and 5/16'' sizes lock onto the wrench with a steel ball detent. A built-in disconnect valve on the core grabber allows core changes without stopping the machine or recovering refrigerant. The set weighs 0.422 kilograms and packs into a 7.08 by 5.90 by 1.57 inch case.
