Fieldpiece GS322C 3-Port Analog Manifold Gauge Set

The GS322C represents a reliable and durable solution for the diagnostics, monitoring, and maintenance of air conditioning systems. Thanks to its 3-port configuration, it allows for the simultaneous monitoring of key system pressures during gas charging, evacuation, recovery, and pressure testing operations. The 80 mm diameter analog gauges are equipped with high-impact boots, ensuring quick and easy readings even under challenging operating conditions.

The unit features a fully sealed SMAN® manifold body with high-quality piston valves for precise refrigerant flow control and long-lasting mechanical durability. The design is engineered to withstand the impacts and wear typical of daily job site use, while the shock-resistant gauge covers and the included heavy-duty carrying case ensure protection and ease of transport.

The GS322C is ideal for residential and commercial HVAC professionals working with modern high-pressure refrigerants, providing a simple yet effective tool for routine HVAC operations.
