PCL Tyre Valve Clip on Connectors 1/4″ Hose ID

A Closed End connector is used when air is supplied
directly from a main air line (i.e. compressor or air
receiver). A non-return valve unseats on connection to
the tyre’s valve allowing air to flow into the tyre.
An Open End connector is used with the MK3 Tyre
Inflator, PCL wall gauges and PCL portable gauges. This
connector has a pin which unseats the tyre’s valve
when is use.
