Which code does this activity belong in?
Gasket, Packing, and Sealing Device Manufacturing (339991) covers establishments that produce gaskets, packing materials, and sealing devices from any material composition. This classification distinguishes these specialized sealing products from fasteners like pins and bolts, which are covered in Fastener, Button, Needle, and Pin Manufacturing. While gaskets and sealing devices serve to prevent leakage in mechanical assemblies, fasteners are used to join components together. All other miscellaneous manufactured products not specifically classified elsewhere fall into All Other Miscellaneous Manufacturing.
