Each valve screws directly onto a charging hose and features a color-coded, one-hand quarter-turn handle and a 45° angled service port to simplify access in tight equipment bays. Constructed from brass alloy with knurled coupler nuts and a green rubber gasket, the set provides reliable sealing at refrigerant pressures encountered in professional and DIY environments.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Aupoko ball valve make refrigerant charging and recovery easier?\u003c\/h3\u003e\n\u003cp\u003eThe valve gives technicians quick, single-handed control to open or stop refrigerant flow without disconnecting hoses, minimizing loss and contamination. The 45° service port improves access to service valves in cramped locations, and the knurled coupling lets you finger-tighten securely for fast swaps.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-hand quarter-turn handle for instant shut-off.\u003c\/li\u003e\n  \u003cli\u003e45° angled service port for easier access in tight spaces.\u003c\/li\u003e\n  \u003cli\u003eKnurled nuts enable quick finger-tight connections.\u003c\/li\u003e\n  \u003cli\u003eGreen rubber gasket reduces leakage risk during service.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat refrigerants and systems are these valves compatible with?\u003c\/h3\u003e\n\u003cp\u003eDesigned as universal low-loss fittings, the valves work with standard HVAC and automotive refrigerants including R134a, R410A, R22 and R12.
