The SEPCO 11 is a 3/4 inch neoprene oval gasket designed for use with conduit bodies in electrical installations. This gasket provides a sealing interface at the conduit body cover, helping to maintain environmental protection within the enclosure. Fabricated from neoprene rubber, it resists moisture, oils, and moderate temperature variation, making it suitable for both indoor and outdoor conduit body applications. Electricians and electrical contractors install this gasket as a replacement or service part during conduit body maintenance or cover replacement on standard 3/4 inch fittings.
This gasket fits 3/4 inch conduit bodies in the miscellaneous conduit body category. It is appropriate for residential, commercial, and light industrial electrical work where a replacement seal is needed at a conduit body junction. The oval profile matches the cover seat geometry typical of standard 3/4 inch conduit bodies, ensuring a proper fit when the cover is secured.
Designed as an OEM-style replacement gasket for standard 3/4 inch conduit bodies requiring an oval neoprene cover seal.
Installation is performed by a licensed electrician. De-energize all circuits and verify the absence of voltage before opening any conduit body. Remove the existing cover and worn gasket, seat the new gasket evenly in the cover groove, and reinstall the cover hardware per NEC guidelines. Do not over-torque cover screws, as this may deform the gasket and compromise the seal.
