Each hose is color-coded (red, yellow, blue) for high\/low\/service lines, features a compact ball valve and female 1\/4\" SAE flare fittings with a valve core depressor and 45° fitting for easier access. Built with a 600 PSI working pressure and a 3000 PSI burst rating, the hoses are suited to common refrigerants—but not recommended for R410A systems, which require higher-pressure hoses.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this hose set help with charging and diagnostics?\u003c\/h3\u003e\n\u003cp\u003eThe LIYYOO hoses let you hook a manifold gauge to system service ports, control refrigerant flow with the ball valves, and depress the valve core for direct access. Their 45° fitting eases connection in tight spaces and the color coding reduces hookup mistakes.
