The TE Connectivity 2-2407269-3 is a protective cap designed for the CPC (Circular Plastic Connector) series, specifically for a size 13 receptacle. It is a red polyethylene (PE) cover that snaps over the receptacle face to shield the contacts from dust, debris, and physical damage when unmated. This cap is a field-service accessory, not a sealing plug — it keeps the connector clean during storage, transport, or panel cutout before harness installation.
This cap fits any TE CPC receptacle with a shell size 13 insert. The shell size is the critical dimension — a size 13 cap will not fit a size 11 or size 17 shell. If you are capping a CPC receptacle on a panel or a free-hanging harness, confirm the shell size marked on the connector body or in the BOM matches 13 before ordering.
Material and duty
The polyethylene material is a standard choice for protective caps — it resists impact and UV exposure, stays flexible enough to snap on and off without cracking, and won't gall the receptacle shell. The red colour makes it easy to spot on a crowded panel or in a tool kit. This is a non-sealing cover; if the application needs an environmental seal (dust or moisture ingress protection), a different cap with an O-ring or gasket would be required.
