High-Pressure Hydraulic Fittings Start with Inspected Steel Bar
Hercules Drawn Steel, part of the Eaton Steel Bar Company, is one of the largest steel bar product companies in the United States. In addition to being one of the largest cold-drawn plants in the country, Hercules also employs state-of-the-art surface inspection systems that were developed in-house as a joint effort with testing equipment manufacturers.
This world-class inspection system allows ESBC to continually exceed customers' demands. This inspection equipment is critical to Eaton Steel, as a leading supplier of raw material used to manufacture hydraulic fittings in North America. Hydraulic hose assemblies allow machines to move fluid from a pump to a wheel, brake, arm, clamp, etc.
The applications for hydraulic hose assemblies are endless; from heavy equipment and off-road vehicles, agricultural equipment, industrial, aviation, and mining equipment, and even the vehicle you drove today.
Hydraulic Fitting Steel Grades
Eaton Steel offers steel for the hydraulic fittings industry. These grades include:
Choosing a Grade for Hydraulic Fittings
- 1215: resulfurized and rephosphorized free-machining steel, a common lead-free choice for fittings and adapters
- 12L14: leaded, resulfurized free-machining steel for high-volume screw machine work where machinability and surface finish matter most
- 41L40: leaded chromium-molybdenum alloy for fittings that need higher strength and fatigue resistance while still machining efficiently

Supply Programs for Fitting Manufacturers
Fitting plants run the same part numbers week after week. Eaton supports that with precision saw cutting, inventory management, and J.I.T. delivery programs so bar is on hand when your screw machines need it. Request a quote with your grade, size, and annual volume, or view current inventory.
Certifications and Documentation
Every steel bar we ship includes certifications and Mill Test Reports documenting the material chemistry, mechanical properties, heat number, and processing history.
Our ISO 9001:2015 certification covers the full order process, including how material is received, inspected against certification documents, stored by grade and heat, and shipped to the customer. That certification gives our customers a third-party validated process behind every order, not just a promise.
