The Robinair High-Side Service Coupler can be used on a wide range of portable air compressors, and is great for general service work. The coupler is mainly used for draining the tank which traps moisture. Connect the Air Coupler between the tanks to drain and expel out any moisture that may have gotten trapped in your tank. This coupler is red in color, which can differentiate it from other similar products that are black or grey.

The high-side service coupler helps to quickly and efficiently perform refrigerant recovery for automotive air conditioning systems during a routine maintenance operation.  The coupler is designed to be hand tightened to the refrigerant line on the vehicle.  The red color makes it easy to differentiate it from black low-side service couplers, helping to prevent the wrong unit from being used on the line.  When using the extender the coupler has a maximum length of 18 inches.  The o-ring at the end of the female service valve can be located and patched before putting caulk over it.

Service coupler replaces the regulation low-side valve. The high-side service coupler is used to work on air tools and other applications that require refrigerant gas to be discharged outside of the system.

This is a factory replacement part for the 30-volt, 4.0-liter air compressor, item AC1234-6.

The ROB18123 is a service coupler that snaps into either port of the high-side manifold (ROB09372 or ROB12133) to provide a convenient connection point for servicing the air system.
