A worn or mismatched tyre valve connector lets air bleed before inflation is complete. The PCL CO5B03 is a short-stem, twin hold-on tyre valve connector with a female Rp 1/4 inlet thread and a closed end, sold as a carton quantity, manufactured in Sheffield since 1938 and part of the HORNGROUP.
The closed-end design means this connector is intended for use when air is supplied directly from a main air line — a compressor or air receiver. On connection to the tyre valve, a non-return valve unseats to allow air to flow into the tyre. The handles on closed-end connectors are red in colour, which provides a clear visual distinction from open-end variants.
For inflation duties fed via an MK3 tyre inflator, PCL wall gauge, or PCL portable gauge, the correct choice is the open-end connector type: those units carry a pin that unseats the tyre valve and are identified by black handles. Selecting the correct type before ordering avoids incompatibility at the point of use.
The CO5B03 is a short-stem variant within the twin hold-on connector range. Where a different stem length or valve style is required, buyers should check the PCL tyre valve connector range for the appropriate alternative.
