Fieldpiece GS334F Analog Gauge Set, 3 Port Manifold for R134A, R404A, R407C, and R448A

Fieldpiece GS334F Analog Gauge Set, 3 Port Manifold for R134A, R404A, R407C, and R448A

The HVACR Tech's Trusted Companion

The Fieldpiece GS334F is a rugged 3-port analog manifold designed for technicians who prefer fast, no-nonsense pressure readings without relying on batteries or menus. Its large, easy-to-read dials, solid piston valves, and reinforced housing make it well suited for charging, recovery, evacuation, and system diagnostics across residential and light commercial systems. With a rotating pressure marker, integrated sight glass, and a compact folding hook, this manifold is optimized for efficiency on the jobsite while holding up to daily wear.

Digital refrigerant manifolds, like the SMAN®, revolutionized the way HVACR techs work - but sometimes the fundamentals get the job done. Whether it's a quick pressure check or a known compressor burnout, every tech has at least one analog gauge set they reach for. And now it can be a Fieldpiece - anything but basic. They're built tough to handle jobsite and service van beatings, include four refrigerants per dial, an integrated sight glass and rotating pressure marker. Make it your go-to gauge set.
