Product details

What This Gasket Seals and Where It Fits

The TE Connectivity 81665-2 is a flange gasket for the CPC (Circular Plastic Connector) series, sized for shell size 17 receptacles with a square flange. Made from black neoprene, it seals the interface between the receptacle flange and the panel, keeping moisture and dust out of the connector cavity. It is designed specifically for CPC receptacles with a square flange — not the round-flange or in-line versions.

Shell Size 17 — The Fit Check

Shell size 17 is the critical dimension. This gasket fits CPC receptacles that carry a shell size 17 designation.

Material and Construction

Neoprene (polychloroprene) gives this gasket good resistance to oils, mild chemicals, and weathering — typical for industrial and outdoor equipment enclosures. The square profile matches the receptacle flange shape, and the gasket compresses evenly when the receptacle is bolted to the panel. No adhesive or additional sealant is needed for a basic environmental seal.
