Appleton GK-12-100 Conduit Fitting

Appleton GK-12-100 Conduit Pull Box Gasket is a 12-inch-long gasket designed for 12‑inch pull boxes used with IMC or rigid conduit. This 1‑inch trade‑size gasket fits pull boxes with screw‑on covers and is manufactured by Appleton for use with rigid metal conduit systems, and is listed for UL fittings for standard conduit box sealing requirements. The GK‑12‑100 is specified for 1‑inch hubs and the pull box opening, helping seal the enclosure and preserve integrity when wiring is pulled through IMC or RMC conduit runs. Ideal applications include commercial and industrial electrical installations where pull boxes serve as access points along conduit runs, such as feeder or branch circuits in rugged environments. Appleton’s GK series is commonly used with PTB/PTC pull boxes to ensure a tight, screw‑on interface and reliable sealing across 12‑inch pull boxes like the GK‑12‑100. This gasket supports 1‑inch trade‑size hubs and is designed for IMC and rigid conduit installations, helping maintain enclosure integrity while cables are pulled through the system.
