• Gauge Reads in Fahrenheit
• R22/134a/404A
• Sliding double “O” ring pistons reduce wear
• Large 3-1/8″ gauges feature steel cases with polycarbonate crystal
• Made in the USA

A manifold gauges are chamber device that is used to control the flows of pressure or gases. The manifold gauge set and interpret the pressures of the air-conditioning system as it operates. A manifold gauges set consists of a manifold block, two hand valves, three refrigerant hoses, and two pressure gauges. The hose on the left is blue and is connected to the low pressure/suction side of the air conditioning system. Because the gauge reads in two different ranges of pressure, it is usually called a compound gauge. The high-pressure side is red coloured.

• The manifold gauge set has two hand valves used to regulate the flow of refrigerant through the manifold.
• The flow control valves within the manifold are closed when the hand valves are turned in all the way in a clockwise direction.
• When the gauge set is installed on a system and both hand valves are closed, the gauges read the pressure exerted on them.
