Robinair 18192 R-134A Manual Replacement Coupler Set – Quick-Connect

Robinair's No. 18192 Field Service Coupler Set is built to connect Enviro-Guard hoses to service ports on automotive R-134a A/C systems. The quick-connect design features an integral safety sleeve that helps protect against injury and refrigerant loss if the coupler disconnects under pressure. The compact form fits into tight engine compartments, making field work smoother in crowded bays.

Inside the set you’ll find one low-side and one high-side manual coupler, both crafted from chrome-plated brass for durability in busy shop environments. The six-ball coupler design delivers a more stable grip on the fitting than four-ball designs, helping technicians work with confidence during connections and disconnections. This is a genuine Robinair replacement part, tested and validated by engineers to help support reliable operation of your RRR equipment.
