It fits shell size 13 receptacles, and the black neoprene material provides a compression seal that keeps moisture and dust out of the connector interface. This is a straightforward accessory — you fit it under the receptacle flange before tightening the mounting screws, and it takes up the gap so the connector stays sealed in damp or washdown environments. ## Shell Size and Fit Shell size 13 is the key fit parameter — this gasket is made for the CPC square-flange receptacle of that shell size. ## Material and Environment Neoprene is a standard gasket material for circular connectors — it compresses under the flange screws, holds its shape over temperature cycles, and resists oils and mild chemicals. For a CPC connector used in industrial control cabinets or light washdown areas, this gasket is what keeps the panel opening sealed. The black color is typical for neoprene and doesn't indicate any special UV or heat rating beyond the material's normal range.","metaTitle":"81665-4 TE CPC Flange Gasket, Shell Size 13, Black Neoprene","metaDescription":"81665-4 TE Connectivity CPC flange gasket, shell size 13, black neoprene.
