It is compatible with all car A/C systems, as well as commercial and domestic A/C and refrigeration systems. The gauges are clearly marked for R134A, R32, R410, and R22 pressure readings, and feature color-coding on gauges, valves, and hoses for easy operation. The set includes a hook, a joint, and three hoses (red, blue, and yellow). Technical specifications Manifold type: 2-way Material: Brass (manifold), Plastic + Metal (hoses) Hoses working pressure: 500 PSI Hoses burst pressure: 2500 PSI Hoses working temperature: -20℃ to 60℃ Usage This tool set is primarily used for the pumping and pressurizing operations in refrigeration maintenance, allowing for refrigerant filling of air conditioning systems while displaying real-time system pressure.
