Hercules OEM Group has worked with a multitude of industries and different seal applications. When you need design assistance, no matter what project, we’ve already got the experience to meet any challenge. Most projects are solved with a simple review and application of standard seal design parameters. For complex problems, we’ll engineer the ideal solution. Call or e-mail our engineers through our “Ask an Engineer” tool.


Hercules OEM Group uses our advanced non-contact visual measurement equipment to take detailed measurements for our customers. Our staff can then reproduce the part in our SolidWorks CAD system. The resultant solid model can then be used to produce parts for cost analysis, design replication or testing validation. Most geometries can be measured without having to cut the part, however more complex shapes will require sectioning.


Material selection is complex and crucial. Each grade of material has a unique set of physical and chemical properties that sets it apart from the others. Our recommendations consider the medium, temperature, static or dynamic motion, maximum operating pressure, environmental aspects, material costs and more. We are experts in all materials, including VitonTM, EPDM, Nitrile, Silicone, PTFE and more.


This process is primarily used in conjunction with an automated manufacturing process. Hercules OEM Group is capable of powder coating parts with several friction reducing substances. This facilitates automatic assembly and can help with identification. Available coatings include talc, silicone, molybdenum disulfide (Moly), and Teflon® coatings. Hercules OEM Group also offers wet coatings.


Hercules OEM Group uses CAD software, specifically SolidWorksTM, to produce solid models and drawings. Solid models are the preferred medium to accurately communicate requirements. Our SolidWorks system can read numerous CAD formats. We also use SolidWorks Product Data Management to tightly control print and model versions. This software assures that the correct version of the print or model is in use at all times.



Tell us how you want it shipped and Hercules OEM Group will deliver to your exact specifications. We can bag the parts in your requested quantities. Our Just-In-Time (JIT) kitting saves you assembly time and overhead by grouping parts together – piston seals, rod seals, wipers, wear guides, O-Rings – any combination you require. We can create customerspecific bags/labels, even barcodes.


Since different part compounds look alike, we can dot them in different colors. It improves quality control by ensuring the correct compound for each application, differentiating expensive parts, and matching correct sizes.


Our worldwide resources, new state-of-the-art warehouse and worldwide delivery expertise enable us to pack, ship and track your order from the moment you place it. We deliver to local areas, nationwide and off-shore anywhere. Our international resources facilitate the process. And we’ll custom kit, bar code, even set up just-in-time (JIT) scheduling.



Our Vendor Managed Inventory (VMI) assures you’ll always have the parts you need. We can stock your specified parts, often ready for same day shipping. We maintain the inventory levels according to your needs. It also lowers in-process/stock-related material costs. We can also facilitate your sales and purchasing process through our Electronic Data Interchange (EDI) system.


EDI speeds up the ordering process, increases accuracy and prevents errors. It allows us to directly translate your sales request into our management software system. It saves the time of working with customer service as orders are electronically put into our system. And since the system is automated, it prevents human error in the transcription process of your order into our system.



Our new inspection facility ensures all incoming products conform to specified requirements. Micro-Vu Non-contact Visual Inspection Devices automatically measure parts for industry standards or your specifications. Shore A/M Durometers measure hardness, a physical property of rubber materials. Measuring specific gravity quickly verifies the compound type.


International Material Data Systems allows indentification of parts or components that may contain hazardous or dangerous substances, like items specified by the RoHS or REACh directives. Our IMDS certification (#55580) is fully proficient in the setup and submittal of materials and components. Most submissions are through the auto industry’s PPAP, but standalone requests are honored.


The Production Part Approval Process specifies the requirements for a new or changed part. It identified any production process weaknesses and assures all design and engineering requirements are met. Documentation includes Failure Mode and Effects Analysis, Control Plan, Process Flow Diagram and Part Submission Warrant.


ISO 9001 Certification demonstrates our dedication to our customers and industry. The international quality system allows us to speak with customers on the same terms. Our focus on continuous improvement assures the most current “best practices,” including warehouse management, information services and delivery strategies. It even assures fair value to customers.


New laws and regulations continuously impact the fluid power and rubber sealing industry. We review new directives to ensure worldwide product compliance. Some common regulatory requests are: Restriction of Hazardous Substances Directive (ROHS); Registration, Evaluation, Authorization and Restriction of Chemicals (REACh); Dodd Frank Conflict Minerals.
