Fieldpiece GS329C A3 Analog Gauge Set - 3 Port
Description
GS329C Fieldpiece A3 Analog Gauge Set, 3 Port, A3, Celsius R600 R1270 R290 R600A
The GS329C is built for technicians working with the full range of today's refrigerants — including A3 hydrocarbon refrigerants like R290 (propane). While most analog gauge sets stop at A2L compatibility, the GS329C goes further, making it the right tool for technicians servicing natural refrigerant systems alongside conventional HVACR equipment.
Like the rest of Fieldpiece's new analog range, it's designed for system diagnostics, refrigerant recovery, pressure testing and charging — with the rugged, no-nonsense build quality the brand is known for.
The rotating pressure marker makes nitrogen pressure testing faster, letting you mark your target pressure before the test and confirm the result at a glance. The integrated sight glass lets you monitor refrigerant flow without guesswork, and piston valves give you precise, consistent control during charging and recovery.
