1/4" Vacuum/Charge Valve with Side Port Kit

Yellow Jacket 18991 RealTorque® 1/4" Vacuum/Charge Valve with Side Port

The Yellow Jacket RealTorque® 1/4" Vacuum/Charge Valve is engineered for high-efficiency evacuation and charging tasks in HVAC systems. Designed with a built-in torque mechanism, this valve ensures proper tightening of the Schrader core to the specified torque range of 3–5 in-lb, reducing the risk of leaks due to overtightening or undertightening.

The integrated side port facilitates direct vacuum gauge connection for real-time monitoring during service, while the valve’s core removal function allows for faster evacuation and recovery times by eliminating system flow restrictions. Constructed for long-term field use, the valve is housed in a protective case for added tool protection during storage and transport.

Key Features

• Torque-Limiting Mechanism: Clicks when 3–5 in-lb is achieved, confirming correct core installation torque
• Side Service Port: Enables vacuum gauge connection without additional adapters
• Core Removal Capability: Improves flow rates during recovery and evacuation
• Protective Storage Case: Rugged case included for transport and job site protection
• Application: Suitable for use on standard HVAC service ports with 1/4" SAE fittings

Specifications

• Port Size: 1/4" SAE
• Torque Specification: 3–5 in-lb (click feedback)

Installation and Use

Installation requires standard HVAC service tools. The torque mechanism eliminates the need for a separate torque wrench during core installation. Use care when removing cores from pressurized systems. Always follow manufacturer safety guidelines and applicable industry procedures.
