Imperial Mechanical 4-Valve Manifold Gauge Set – R410A/R22/R134a, Sight Glass, Aluminum Body, High-Precision Analog Gauges

Imperial Mechanical 4-Valve Manifold Gauge Set – R410A/R22/R134a, Sight Glass, Aluminum Body, High-Precision Analog Gauges

Condition: Used. Shows signs of field use including scuffs or light discoloration. Gauges and valves appear intact.

The Imperial Mechanical Manifold Gauge Set (4-Valve configuration) is a professional-grade HVAC/R service tool, ideal for charging, recovery, and system diagnostics of refrigerants including R-410A, R-22, and R-134a. This heavy-duty set features a rugged anodized aluminum manifold block with precision-machined internals and oversized handwheels for maximum control under pressure.
The 4-valve design enhances flexibility during vacuum, charging, and recovery operations by adding a dedicated valve for vacuum pump or recovery machine connection. It reduces cross-contamination and makes the evacuation and charging processes faster and more efficient. The integrated sight glass aids in monitoring refrigerant flow and moisture or contaminant presence during system servicing.
