Yellow Jacket 18971 4-in-1 Vacuum Charge Valve 1/4 Inches

Product Description

The YELLOW JACKET 18971 is a 1/4-inch 4-in-1 ball valve tool designed for HVAC refrigeration service work. It handles four core functions in a single unit: vacuum, charge, Schrader core removal, and refrigerant recovery. The design allows technicians to remove and replace Schrader cores without losing system charge, saving time and reducing refrigerant loss on every service call. This valve is built for field use and is a practical addition to any HVAC service technician's manifold setup or recovery rig. No side port is included on this version.

This valve is used in residential and light commercial HVAC refrigeration service applications. It is suited for tasks that require pulling a vacuum, charging a system, performing core removal, or connecting recovery equipment — all through a single connection point. The 1/4-inch fitting size is standard for most refrigerant manifold hose connections, making it compatible with typical field service setups. HVAC technicians performing routine maintenance, system commissioning, or refrigerant recovery will find this tool applicable across a wide range of service scenarios.

Installation Notes

This valve is installed and serviced by licensed HVAC technicians working with refrigerant systems. Always recover refrigerant and follow EPA Section 608 regulations before opening any refrigerant circuit. Ensure all connections are hand-tight and leak-checked before pulling vacuum or introducing charge. Do not exceed the rated working pressure of the connected system or service hoses.
