Pneu-Draulics Inc. operates as a manufacturer and distributor of custom fluid power components, supporting both OEM production lines and MRO aftermarket needs. As dedicated sealing specialists, we engineer custom solutions that bridge the gap when standard catalog parts fail to meet application requirements or lead-time constraints. From rapid prototyping to large-diameter manufacturing, our facility provides the specialized engineering support and Machining capabilities required to keep your critical industrial systems online.

Our Capabilities for Non-Standard O-Ring Sizes

Finding replacement parts for obsolete, heavy-duty, or specialized machinery often introduces significant production bottlenecks. When standard metric or imperial profiles do not match your equipment configurations, waiting on factory lead times from primary manufacturers can stall operations for weeks.

Pneu-Draulics mitigates this logistical risk by manufacturing non-standard O-ring sizes in-house. Supported by two regional inventory warehouses, our production capabilities allow us to process elastomeric compounds quickly, matching your precise hardware dimensions without long factory lead times.”

Sealing Design

Matching the correct elastomeric polymer to specific chemical, thermal, and pressure parameters is critical to preventing premature component failure and fluid leaks. Our engineering team provides comprehensive custom seal design services to help your technical personnel isolate and select the optimal material compound for challenging operating environments.

Beyond molded geometries, our production technicians perform precise custom gasket cutting services. This specialized processing allows us to convert raw sheet stock into custom flat seals that match unique flange profiles, mating surfaces, and bolt-hole configurations.

Product Engineering/Prototyping

Testing physical components before launching full-scale production protects your project budget. We execute rapid machined rubber seal prototyping to deliver testable components directly to your facility. Our machinists also build exact machined PTFE seal profiles designed to withstand aggressive chemicals and extreme temperatures in heavy-duty applications.

Custom Packaging & Labeling

Managing bulk industrial components creates significant tracking and logistical overhead on the factory floor. To streamline your internal supply chain, we adapt our delivery and processing configurations to align directly with your facility’s receiving protocols.

Our technical packaging options include:

  • Custom labeling. Application of your internal cross-referenced part numbers, internal SKUs, and standard barcodes directly to individual or batched packaging to minimize inventory intake errors.
  • Specialized packaging. Sealing sensitive elastomeric components in protective, opaque barrier materials to prevent premature ultraviolet (UV) degradation, ozone exposure, or moisture contamination during storage and transit.

Machining and Manufacturing

Our ASAP branch executes the reliable CNC seal manufacturing that Alabama engineers rely on for rapid component delivery. We perform precise custom U-cup machining to build specific directional seals. Our heavy-duty equipment produces custom-machined seals 57” across for massive fluid power systems and creates robust, large-diameter industrial seals. When your machinery breaks down unexpectedly, we deploy emergency hydraulic seal machining to fabricate replacement parts immediately and restore your operational capacity.

Custom Kitting

Maintenance teams waste valuable time gathering individual O-rings and backup rings for scheduled overhauls. We group all the necessary replacement parts for a specific cylinder or valve into a single, labeled package. Delivering these complete repair kits directly to your maintenance department speeds up equipment repairs and eliminates missing components.
