Fieldpiece GS422C / GS434C / GS429C 4-Port Analog Manifold Gauge Sets

The Fieldpiece GS Series represents a comprehensive pressure measurement solution for HVAC/R systems, featuring a design engineered for intensive professional use. All models are equipped with a 4-port analog manifold, allowing for the simultaneous management of multiple service lines during system charging, recovery, evacuation, and diagnostics.

The manifold body features a rugged, leak-proof construction designed to withstand vibrations, impacts, and harsh operating conditions. The large-diameter analog gauges ensure quick and precise readings even in low-light environments or on the job site. High-smoothness piston valves provide fluid refrigerant flow control and superior durability compared to traditional systems.

Model Specifications:

• GS429C: Dedicated to Class A3 flammable refrigerants, ideal for hydrocarbon-based systems such as propane and isobutane.

• GS434C: Designed for commercial and industrial refrigeration systems, compatible with both traditional and next-generation refrigerants.

• GS422C: Engineered for residential and commercial A/C applications, covering the most widely used refrigerants in the HVAC sector.

All sets are supplied with a professional heavy-duty carrying case, protecting the instrument during transport and facilitating equipment organization in the workshop or service vehicle.
