Feature: 1. Rubber material possess anti-corrosion, stable performance. Pure brass joints with high tightness 2. AC charging hose possess compact structure, light weight, easy to install and use 3. Ball valve design, only need to turn a quarter of the valve handle to control the refrigerant 4. Diaphragm valve is equipped with rotating seals, which has stronger sealing performance and less wear 5. Widely used in the refrigerant filling of automobile refrigeration, accurate air conditioners, industrial air conditioners and other equipment Specification: Item Type: AC Charging Hose Material: Rubber + brass Model: CT-360RYB (R22) Uses: Widely used in the refrigerant filling of automobile refrigeration, accurate air conditioners, industrial air conditioners and other equipment Scope of Application: Used to transport refrigerants such as R12, R134a, R410a, 502, 404, etc. Working Pressure: 500PSI Burst Pressure: 2500PSI Working Temperature: -30~+110℃ Hose Hardness: 70 ± 5℃ Hose Length: Approx. 1.5meter / 4.9ft Specification: Red, yellow, blue Connector: 1/4inSAE, 5/16inSAE. Package List: 3 x AC Charging Hose Note: 1. Empty first (the connecting pipe between the refrigerant tank and the machine is first to use the refrigerant to exhaust the air inside).2. For the mixture (R410A, R407C), it must be charged in a liquid state. Make sure that the refrigerant is charged in a liquid state. For R22, gaseous and liquid is fine, but the gas charge is slow.
