Heatcraft 5731V 1/4 Flare Valve Core Fitting for Commercial Refrigeration

The Heatcraft 5731V is an OEM replacement 1/4" flare valve core fitting designed for use in commercial refrigeration systems. This service access fitting provides a reliable, leak-tight seal at refrigerant service ports, allowing HVAC/R technicians to perform system charging, evacuation, pressure testing, and diagnostics without interrupting system integrity.

The Schrader-style valve core remains closed under system pressure and is depressed only when a service hose fitting is connected, making it safe and efficient for routine maintenance procedures. Replacing a worn or damaged valve core is a fast, cost-effective repair that restores proper sealing at the access port without requiring replacement of the entire fitting assembly.

Key Features:

• OEM Heatcraft replacement part — ensures proper fit and function
• 1/4" SAE male flare connection for compatibility with standard refrigeration service equipment
• Schrader-style core design stays closed under system pressure until depressed by a service hose
• Compatible with a wide range of common refrigerants including R-22, R-134a, R-404A, R-410A, and others
• Sold individually (each)

The Heatcraft 5731V valve core is an essential service component for maintaining the integrity of refrigerant access ports on Heatcraft commercial refrigeration equipment. Keeping spare valve cores on hand reduces downtime during routine service calls.
