The J/B Industries A31201 is a professional-grade access valve designed for HVAC and refrigeration service work. Access valves are essential components in refrigerant circuit servicing. They allow technicians to connect gauges, charge refrigerant, recover refrigerant, and check system pressures without permanently altering the sealed system. The A31201 provides a reliable service port that HVAC technicians, refrigeration mechanics, and service professionals depend on during routine maintenance and emergency repairs.
Access valves are threaded or clamped onto refrigerant lines, compressor service ports, or system access points. Once installed, they create a leak-tight seal that opens only when a manifold gauge set or service tool is connected. This design keeps the refrigerant circuit sealed during normal operation and ready for service when needed. The A31201 is built to handle the pressures and temperatures common in residential and commercial refrigerant systems, including those using R-410A, R-22, R-134a, and similar refrigerants.
J/B Industries is a well-known manufacturer of HVAC service tools and components. Their access valves are trusted by contractors and technicians who require dependable, long-lasting service hardware. The A31201 is a practical solution for new installations and field repairs alike. It is compatible with standard manifold gauge hose fittings, making integration into any technician toolset straightforward.
