The NESCO SR-40 combines a steel retainer ring and integrated seal into a single component for 4" rigid conduit entries, eliminating the need for separate sealing hardware. Designed for use in electrical enclosures, junction boxes, and conduit systems, it delivers a reliable, weathertight connection that meets the demands of commercial and industrial installations. Its one-piece construction speeds up installation and reduces the risk of improper sealing on the job site.
