The HUBBELL OLK3VG is a 1-inch fiber gasket designed to create a secure, leak-resistant seal in electrical enclosures, conduit fittings, and related trade assemblies. Fiber gaskets provide reliable compression sealing between mating surfaces, preventing moisture ingress and maintaining enclosure integrity. This part is typically installed by licensed electricians during conduit assembly or enclosure work where a compliant, durable seal is required at a 1-inch fitting or knockout.
This gasket is suited for use in residential and commercial electrical installations where 1-inch conduit fittings, hubs, or enclosure knockouts require a compressible sealing element. It is commonly used during new construction, retrofit work, and maintenance service on electrical distribution enclosures and junction boxes.
Designed as an OEM-style replacement or service gasket for 1-inch electrical enclosure fittings and conduit hubs requiring a fiber sealing element.
Installation is typically performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and confirm the enclosure is de-energized before beginning work. Seat the gasket evenly between mating surfaces and tighten the fitting to the manufacturer-specified engagement without over-torquing, which can crush the fiber material. Inspect the gasket for cracks or compression set before reuse during any maintenance service.
