ATD Tools R134a Low Side Manual Quick Coupler 14mm-F x 13mm — ATD-3652

The ATD Tools ATD-3652 is an R134a low-side manual quick coupler (14mm-F x 13mm) for connecting manifold gauge sets to vehicle low-pressure A/C service ports. Reliable, leak-free connection for R134a system diagnosis, evacuation, and charging. Ships nationwide.

The ATD-3652 is an R134a low-side manual quick coupler for technicians who need a dependable, positive-locking connection between a manifold gauge set and the vehicle’s low-side service port.

14mm female to 13mm low-side R134a quick coupler. Manual operation provides positive-locking confirmation before refrigerant flow. Direct replacement for worn low-side couplers on existing gauge sets.

Compatible with standard 13mm R134a low-side service ports on domestic and import passenger cars and light trucks (1994–2021). Low-side only — not for high-side, R-12, or R-1234yf ports, as well as lift trucks, agricultural equipment, on/off-highway diesel vehicles.

ATD Tools manufactures A/C service fittings for daily shop use — individual coupler replacements support technicians maintaining existing gauge set equipment.

Ships nationwide. Order the ATD-3652 and maintain a leak-free low-side connection.
