The Single Clip-on Connectors are suitable for use in tire shops.

There are two types of connectors. It is, therefore, important when purchasing connectors to specify whether a closed or open-end type is required.

A Closed End connector is used when air is supplied directly from the main air line (i.e., compressor or air receiver). A non-return valve unseats on connection to the tire's valve, allowing air to flow into the tire.

An Open End connector is used with the MK3 Tyre Inflator, PCL wall gauges, and PCL portable gauges. This connector has a pin that unseats the tire's valve when is used.

The Single Clip-on Connector is available in both the Closed and Open end valve styles.
