Fieldpiece gs322f 3-port Analog Manifold Gauge Set

Product Description

The FIELDPIECE gs322f is a 3-port analog manifold gauge set designed for HVAC-R technicians performing system diagnostics, refrigerant recovery, pressure testing, and refrigerant charging. It features four refrigerant saturation temperature rings and a rotating pressure marker, allowing techs to read saturation temperatures directly off the gauge face without a separate chart. The set supports four common refrigerants: R-22, R-32, R-454B, and R-410A. Maximum working pressure is 800 psi, and accuracy is rated at plus or minus 1 percent. All connections are 1/4 inch SAE male flare, the standard for residential and light commercial HVAC-R service work.

The gs322f is suited for residential and light commercial HVAC-R service calls where analog gauge sets are preferred for their simplicity and reliability. It is appropriate for any application involving the four listed refrigerant types, including legacy R-22 systems, R-410A equipment, and newer low-GWP refrigerants R-32 and R-454B. The rotating pressure marker and printed saturation rings make it practical for rapid field diagnostics without additional reference tools.

Key Features

• Supports R-22, R-32, R-454B, and R-410A refrigerants on a single gauge set
• Four refrigerant saturation temperature rings for direct on-gauge temperature reference
• Rotating pressure marker to flag target pressures during service
• 800 psi maximum working pressure
• Plus or minus 1 percent accuracy rating
• 1/4 inch SAE male flare connections on all 3 ports

Compatibility

Designed for use with R-22, R-32, R-454B, and R-410A refrigerant systems using standard 1/4 inch SAE male flare service ports, typical of residential and light commercial HVAC-R equipment.

Installation Notes

Installation and use of manifold gauge sets should be performed by EPA Section 608 certified technicians. Before connecting or disconnecting the gauge set, ensure the system is at a safe service pressure and follow all applicable local refrigerant handling regulations. Inspect hose connections and valve seats for wear or contamination before each use to prevent cross-contamination between refrigerant types. Do not exceed the 800 psi maximum rated working pressure of this gauge set.
