This is a refrigerant charging hose with a built-in pressure gauge for adding refrigerant to air conditioning systems. It works with R134a, R12 and R22 refrigerant systems, for car and home AC maintenance.
The low-pressure gauge is color-coded and reads 0-350 PSI, so you can monitor system pressure while charging. The hose connects to the vehicle with a 13 mm R134a low-side quick coupler. A can-tap valve is built in, so the hose connects directly to a can of refrigerant.
The hose is flexible rubber with corrosion-resistant metal fittings, made to withstand high pressure and frequent use. Use it only on the low-pressure side of the AC system. Connecting to the high-pressure port is dangerous and can cause injury. Wear safety glasses and gloves when working with refrigerants. Keep the engine and AC compressor running as the refrigerant manufacturer instructs during charging.
