Accessories that Complete Your Conduit System Installation

Heyco’s electrical reducing washer and conduit sealing washer solutions enable proper fitting installation when panel knockout sizes don’t match conduit fitting threads, or when additional environmental sealing is required for wet location compliance.
A 3/4 to 1/2 reducing washer allows installation of 1/2″ NPT fittings in 3/4″ panel knockouts, eliminating panel modification or oversized fittings. Conduit sealing washers provide additional liquid tight protection between fittings and panels, ensuring NEMA-rated environmental sealing in outdoor and wet location applications.
