CPC Plug Cap — Shell Size 11, Black Polyethylene
The TE Connectivity 2407269-2 is a protective cap from the CPC (Circular Plastic Connector) series, designed specifically to cover a CPC plug connector when unmated. It fits Shell Size 11 plugs, keeping the contact face clean and protected from debris, dust, and mechanical damage during storage or when the connector is not in use. The cap is moulded in black polyethylene (PE), a lightweight, non-corrosive material that resists common shop fluids and won't gall the plug threads.
Shell Size 11 — Fits the Plug, Not the Receptacle
The Shell Size 11 designation is the critical dimension — this cap mates with the outside diameter of a CPC plug shell of the same size. It is not a cap for the receptacle or panel-mount half. If you're capping a CPC plug on a harness, this is the right shell size.
