• •▶Including 3 5-feet color-coded Freon_ charging hoses for easy recognition, the red for high pressure, blue for low pressure, and yellow for refrigerant bottle. The max working pressure of hose is 600PSI and bursting pressure is 3000PSI, which ensures long durability. Anti-corrosion, low fluid resistance, high bearing pressure, and good air sealing are also important features of the hoses.
• •▶Double movement gauges are much more sensitive. The blue low pressure gauge with range 0-250PSI, and red high pressure gauge with 0-500PSI. The gauge has Fahrenheit degree unit and easy-to-read instrument panel. Built-in precision components ensure measurement accuracy.
• •▶Manufactured by solid brass, aluminum, PVC and plastic, the gauge can stand up to heavy use and accidental drops, which is a ideal tool for professional auto mechanics. It also includes a detailed parts diagram and step by step instructions to help novice.
• •▶Through the transparent sights window, you can distinctly see when the charging status.Package with 5Ft long enough 3 color charging hoses, thickening hose body with precise valve core depressor and 45 degree bend on one end for convenient accessing. Hose rated 600Psi max working pressure and 3000Psi bursting pressure. Before using, please connect the blue hose to low pressure connector, red hose to high pressure connector and yellow hose to charge/release connector.
• •▶Professional 3-way air conditioning diagnostic manifold gauge set is designed for AC charging, diagnostic check and recovery work, and it is applicable for R134A, R12, R22 and R502 refrigerants.These are heavy-duty hoses which can last for years, never worry about bursting again .
