Built from aluminum, bronze and brass components, the fittings are intended to streamline charging and service work on automotive and HVAC R134a systems by providing a durable, snap-lock connection and a reversible ACME tank interface.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the adjustable quick coupler work with my car's A\/C service ports?\u003c\/h3\u003e\n\u003cp\u003eThe couplers attach directly to factory R134a service nipples: blue to the low side and red to the high side. Each coupling uses a knurled grip and snap-lock mechanism so you can push on and release with confidence, minimizing refrigerant loss during connect\/disconnect.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eColor-coded blue (low) and red (high) for fast identification.\u003c\/li\u003e\n  \u003cli\u003e1\/4\" SAE male flare interface fits standard manifold hoses and gauges.\u003c\/li\u003e\n  \u003cli\u003eKnurled ring and snap-lock provide secure, tactile engagement.\u003c\/li\u003e\n  \u003cli\u003eDetachable adapter portion simplifies cleaning and upkeep.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan this kit adapt older can taps or different refrigerant tools?\u003c\/h3\u003e\n\u003cp\u003eThe included brass R134a tank adapter bridges ACME-style refrigerant cans to 1\/4\" flare hoses so you can use common can taps and service tools with R134a cylinders.
