CarBole Refrigerant Low and High Pressure Gauges 11.2mm for Air Conditioner R410A R134A R22 PSI KPA (Low and High Gauges)

Product description

Great for a manifold with 1/8 NPT thread.

The operating temperature is -40 to 70 cesius degrees. This pressure gauge is suitable for plumbing. heating. air conditioning. pneumatic. hydraulic. water tanks. and air compressors.
Pressure gauges are instruments used to measure the pressure of a gas or liquid inside a vessel and. often. to help ensure the optimal amount of pressure for a given application. Pressure gauges can range from everyday instruments. such as those used to measure the air pressure in a car or bicycle tire. to highly accurate gauges used in mechanical and industrial processing. Most often. pressure gauges measure pressure relative to another reference. For instance. gauge pressure measures pressure relative to ambient air. An example of a pressure gauge measuring relative to ambient air is a tire pressure gauge or a blood pressure gauge. Differential pressure is the difference in pressure between two points. such as when measuring liquid flow along various points in a pipeline. An absolute pressure gauge measures pressure relative to a perfect vacuum. such as an atmospheric or barometric pressure gauge.
