The TE Connectivity 796075-1 is a sealing plug for the CPC (Circular Plastic Connector) series. It is not a connector body or terminal — it is an accessory that seals unused contact cavities in a mated CPC connector assembly. Made from natural polypropylene (PP), it plugs into the rear of a CPC connector housing where a contact would normally sit, preventing moisture, dust, and debris from entering through empty positions. The natural color provides a visual cue during harness assembly and field service — you can spot an unsealed cavity at a glance. The polypropylene material offers good chemical resistance and a wide operating temperature range typical of CPC connectors, though the exact temperature limits depend on the mated connector assembly.
Compatibility — Which CPC Connectors Does It Fit?
The 796075-1 is designed for use with TE Connectivity CPC connectors, but it is not a universal fit for every shell size or contact arrangement. CPC connectors come in multiple shell sizes (11, 13, 17, 23, 28) and contact cavity layouts. This sealing plug is sized for a specific cavity diameter — typically the standard signal contact cavity. It will not seal a power contact cavity or a larger shell cavity without the matching contact bore. Verify that the plug diameter matches the unused cavity in your specific CPC connector housing before ordering.
