What This Seal Kit Does in the Assembly
The TE Connectivity 213919-2 is a wire entry seal kit for the CPC (Circular Plastic Connector) series, shell size 17-14. It is an accessory — not a connector body — that seals the rear of a CPC plug or receptacle housing where the wires exit. The black silicon gasket compresses against the cable bundle when the pressure plate is tightened, keeping moisture and dust out of the backshell. This is the part you add when a standard CPC housing needs an environmental seal at the wire entry point, common in industrial control cabinets, washdown zones, or outdoor equipment where the connector faces spray or condensation.
Shell Size Fit and Compatibility
The shell size 17-14 designation means this kit fits CPC housings with that insert arrangement — typically the medium-frame circular bodies that carry 14 to 19 signal or power contacts depending on the insert layout. It is explicitly listed for use with CPC plug and receptacle housings of the same shell size.
Material and Construction
The seal element is silicon — a material chosen for its flexibility across temperature swings and its resistance to compression set over time. Silicon holds its seal after the pressure plate is torqued down, unlike some rubber compounds that take a set and leak after a few thermal cycles. The pressure plate is included in the kit, so you do not need to order a separate retaining component. The housing is black, which matches the standard CPC colour scheme for the shell.
It is supplied in bulk packaging. No official cross-reference or successor is recorded, so if you need this shell size seal kit, the 213919-2 is the direct TE part number to specify.
