The refrigeration gauge is a reliable refrigeration gauging device designed to measure the pressure of non-corrosive, non-crystalline and high-viscosity liquids or gases. Though sharing some common properties with diaphragm pressure gauges, this pressure gauge is highly resistant to pressure pulses, strong impact and vibration.

This liquid filled gauge is a pressure gauge with the following advantages
1. The liquid absorbs vibration and pressure spikes.
2. The dampening action of the liquid helps operators to take the reading of the pressure in conditions of rapid and dynamic loading and vibration.
3. There is less chance for abrasion as all moving elements are lubricated.
4. Since the entire gauge has a hermetic structure and is filled with non-aqueous liquid, it is resistant to moisture, ice formation and rust.

This refrigerantcharging hose is built to be durable and long lasting. The hose can come in different lengths and is made of natural rubber and brass. It's used in working conditions where the temperature ranges from -30 to 100 ℃.

As the rubber lining interior and protective layer are highly resistant to oils and leak-proof, this industrial hose works well for refrigeration and air conditioning systems. We can also customize hoses for customers' different products. A number of sealing gaskets are also available.

Applicable refrigerants: R22/ R134a /R404a/ R407c/ R502/ R410a;
Working pressure: 600psi~3000psi or 800psi~4000psi;
