What This Cap Protects and Where It Fits
The TE Connectivity 4-2407269-2 is a protective cap designed for the CPC (Circular Plastic Connector) series, specifically for size 17 receptacles. It covers the mating face of the receptacle when unmated, keeping dust, debris, and incidental contact off the contacts during storage, shipping, or service intervals. The cap is molded from black polyethylene (PE), a material chosen for its impact resistance and chemical inertness in industrial environments.
Compatibility — Which Connector It Fits
This cap is specified for use with CPC receptacles in shell size 17. The shell size is the critical dimension — size 17 defines the outer diameter and thread pattern of the receptacle flange. If you have a CPC receptacle marked size 17, this cap will seat over the mating face. It is not designed for size 11, 13, or 23 shells, nor for CPC plugs (which use a different cap profile).
Material and Construction
Molded from polyethylene (PE), the cap is a single-piece part with no metal inserts or gaskets. The black color provides UV resistance for applications where the cap may see sunlight exposure during storage.
