The company's main focus is to minimize down time to high dollar, revenue generating equipment by offering most orders next day. Hercules is also a growing force in OEM and special aftermarket kits for major cylinder manufacturers.

Hercules target markets include hydraulic equipment in dump truck, refuse collection, construction (both on and off road) material handling (lift trucks), farming, logging, and industrial plant applications. Replacement seals, seal kits and hydraulic cylinders are stocked for well known names such as Caterpillar, J.I. Case, John Deere, Komatsu, Nissan, Toyota, and many others. Hercules sells the highest quality inch and metric sized seals produced by the world's leading manufacturers and is also an authorized distributor of hydraulic cylinders manufactured by Parker, Commercial, Custom Hoists, and Hyco.

Hercules publishes the largest single source catalog of individual seals, replacement parts, and technical information in the industry. Products in Canada are sold in Montreal and Toronto through Hercules Sealing Products Canada, a wholly owned subsidiary.
