What This Gasket Is and Where It Goes
The TE Connectivity 1445420-2 is a flange gasket for the Miniature CPC (Circular Plastic Connector) series, shell size 11. It is a sealing accessory — not a connector body — that fits between the connector flange and the panel face when the connector is mounted through a cutout. The gasket is moulded from black neoprene, a synthetic rubber chosen for its resistance to oil, ozone, and moderate temperature swings. The jam nut feature means this gasket is intended for panel-mount installations where the connector is secured from the rear with a jam nut, compressing the gasket against the panel to form a seal.
Shell Size and Fit — Why It Matters
The shell size 11 is the critical fit parameter. This gasket is dimensioned to match the panel cutout and flange profile of a Miniature CPC connector with shell size 11.
Material and Environmental Resistance
Neoprene (polychloroprene) is a gasket material used in industrial and automotive connector applications. It holds up against oil mist, mild chemicals, and UV exposure better than natural rubber or EPDM in many panel-mount environments.
