Car AC Recharge Kit | R134A Quick Couplers | H/L Manifold Gauge Adapters

This R134a quick coupler set connects your AC manifold gauge to a car's air conditioning system. The adjustable fittings snap onto the high and low-side service ports. This makes checking and recharging refrigerant simple. Features and Benefits - Color-coded knobs - The red coupler goes on the high-side port, and the blue one goes on the low-side. This stops you from connecting them wrong. - Adjustable valve control - A knob on top opens and closes an inside valve. This lets you control refrigerant flow without taking off the hose. - Solid brass body - The metal body won't rust or wear out from using it a lot. It gives a good seal every time. - 1/4" SAE male flare fittings - This is a standard connection size. It works with most AC manifold gauge hose sets for car work. Applications - Checking AC system pressure problems by connecting a manifold gauge set. - Recharging a car's R134a refrigerant system safely and well. - Taking out and getting back old refrigerant from a car AC system before repairs.
