PVC Insulated Flexible Electrical Conduit

Flexible electrical conduit tubing made of galvanized steel lined with PVC insulating material, used to protect wiring in industrial machinery. It falls under HTS 8547.90.00 as electrical conduit tubing of base metal lined with insulating material, distinct from unlined metal conduit or ceramic insulators. The metal core provides structure while the PVC lining ensures electrical insulation.

Galvanized Steel Insulated Conduit Joint Coupling

Couplings for joining insulated electrical conduits, featuring steel body lined with polyethylene insulator for secure, insulated connections in equipment wiring. Classified under HTS 8547.90.00 as joints for electrical conduit tubing of base metal lined with insulating material. The minor metal threads aid assembly while insulation prevents shorts.

Epoxy Insulated Motor Terminal Bushings

Bushings for electric motor terminals made of phenolic resin insulation with minor threaded metal inserts for mounting, preventing electrical arcing in appliances. HTS 8547.90.00 covers these as insulating fittings wholly of insulating material (minor metal for assembly) for electrical machines. They insulate high-current connections safely.

Silicone Rubber Insulated Cable Glands

Cable entry glands with aluminum base metal body lined/compressed with silicone rubber insulation for watertight, insulated wire entry into electrical enclosures. Under HTS 8547.90.00 as insulating fittings for appliances with minor metal for assembly. Provides strain relief and insulation in harsh environments.
