Summary
The APEX Design USA Quick Connect Y splits one air connection into two 3/8 inch barbed lines. It connects directly to the Panel Mount fitting, the Precision Tyre Inflator and the On/Off Valve, which makes it the branching piece for building out a multi-line air system - one source in, two lines out, quick-connect convenience where it plugs in.
Best For
- Building or extending a multi-tyre air harness from APEX components

Any point where one air feed needs to become two - typically splitting a panel port or inflator feed into lines serving both sides of the vehicle.
Pair it with the panel mount fitting and the air system starts looking factory-fitted.
