It threads onto the plug housing to lock the mated pair and compress the interfacial seal. The black nylon body gives it a light, corrosion-resistant shell that handles the torque of hand-tightening without galling against the connector threads. This is the ring that secures the cable-side half to the panel-mount receptacle in a CPC interconnect. ## Shell Size and Material Fit Shell size 11 is the standard insert dimension for CPC connectors in this class — it matches the coupling thread diameter of the corresponding plug and receptacle. The nylon material keeps the ring non-conductive and avoids the galvanic corrosion issues a metal ring would introduce in a mixed-material assembly. Black color is the standard finish for the CPC line; no secondary marking is needed for visual identification on the harness.","metaTitle":"TE 213811-1 CPC Coupling Ring, Shell Size 11, Black Nylon","metaDescription":"TE Connectivity 213811-1 CPC coupling ring, shell size 11, black nylon.
