There are two types of connector. It is therefore important when purchasing connectors to specify whether a closed or open end type is required.
An Open End connector is used with MK4 Tyre Inflator, PCL wall gauges and PCL portable gauges. This connector has a pin which unseats the tyre's valve when is use. The handles on these connectors are black in colour.
An open ended air inflator has no control over the airflow, air will flow freely unless connected to a trigger etc.
