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.

Digital Air Conditioner Charging and Testing Manifolds
Monitor refrigerant pressure on an LCD when servicing air conditioning systems. This manifold automatically calculates how much refrigerant is needed in a system based on measurements taken with its thermocouples.

Threaded Precision Flow-Adjustment Valves with Gauge Ports
- Valve Type: Needle
- For Use With: See table
- Seal Material: Fluoroelastomer Rubber
With a gauge port on each side of these valves, you can install two pieces of instrumentation equipment to simultaneously monitor multiple media properties without interrupting flow. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Valves have a 316 stainless steel body for excellent corrosion resistance.
Metal-to-metal seats resist temperature fluctuations.
Bubble-tight soft seats provide a tighter seal than metal-to-metal seats when the valve is completely closed.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
