Packings-Mechanical (Wholesale) is a subdivision of the Industrial Machinery and Equipment Merchant Wholesalers industry. This industry involves the wholesale distribution of mechanical packings, which are materials used to seal gaps between two or more surfaces in order to prevent the escape of fluids or gases. These packings are used in a variety of applications, including pumps, valves, and other mechanical equipment. Companies in this industry typically purchase packings from manufacturers and then distribute them to other businesses, such as manufacturers, repair shops, and maintenance departments.
