Fieldpiece GS422F Analog Gauge Set, 4 Port Manifold for R22, R32, R454B, and R410A

Fieldpiece GS422F Analog Gauge Set 4 Port Manifold for R22, R32, R454B, and R410A

The HVACR Tech's Trusted Companion

The Fieldpiece GS422F is a 4-port analog refrigerant manifold engineered for HVACR professionals who want complete system access with rugged simplicity. This classic analog manifold expands your diagnostic reach with four service ports — perfect for charging, pressure testing, recovery, and advanced diagnostics — while offering clear, dependable readings without batteries or digital screens. Built with durable components and intuitive controls, the GS422F enables seamless service on residential and commercial systems. Whether you're establishing baseline pressures or fine-tuning a charge, the GS422F is built to withstand daily use in tough environments.

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.
