Fieldpiece GS422C 4-Valve Analog Refrigerant Manifold – R22, R32, R454B & R410A

GS422C

Australian model - Celsius/Bar/PSI

The Fieldpiece GS422C 4-Valve Analog Refrigerant Manifold is designed for HVAC and refrigeration technicians who need a reliable 4-port analogue manifold for service, charging, recovery, evacuation, pressure testing and diagnostic work. Suitable for R22, R32, R454B and R410A refrigerants, this manifold is ideal for air conditioning, heat pump and general HVAC/R service applications.

Built around Fieldpiece’s pressure-tight SMAN manifold block, the GS422C combines traditional analogue gauge reliability with modern jobsite durability. The Class 1A gauges provide clear pressure readings, while the integrated sight glass allows technicians to visually check refrigerant flow during charging and recovery work.

The GS422C features high-grip valve knobs, precision piston valves, swappable hose seats, a folding hook and robust protective gauge bumpers. With three 1/4" SAE male flare refrigerant ports and a dedicated 3/8" SAE evacuation port, it is a practical 4-port manifold for HVAC service vehicles, workshops and maintenance teams. Hoses are sold separately unless supplied as part of a selected bundle.
