Air Conditioner Charging and Testing Manifolds
Monitor refrigerant pressure with analog gauges when servicing air conditioning systems. All manifolds have double O-ring piston valves. Manifolds with sight glass allow you to view liquid levels.
Replacement gauges are sold separately.
Optional gauge cover sets (sold separately) include one blue and one red gauge cover. They are not for use with the manifolds for R-410A refrigerant.

Refrigeration Pressure and Vacuum Gauges
Often used with chillers and in refrigeration systems, these gauges display the temperature of ammonia relative to the pressure measurement. Also known as compound gauges, these measure both pressure and vacuum.
