HARRINGTON INDUSTRIAL PLASTICS LLC

Harrington Industrial Plastics LLC specializes in the design and fabrication of precision polymer components for naval vessel systems, with demonstrated expertise in fluid handling infrastructure for U.S. Navy platforms. Their core capability centers on manufacturing high-performance industrial plastic parts such as simplex strainers, engineered to meet stringent marine environment requirements including corrosion resistance, flow optimization, and long-term durability under dynamic operational loads. The company applies advanced thermoplastic molding and machining techniques to produce mission-critical filtration and flow control components that integrate seamlessly into shipboard piping systems, ensuring reliability in harsh, saltwater-exposed environments. Their technical proficiency lies in material selection for marine applications, tight-tolerance machining of polymer assemblies, and adherence to military specification standards for component performance and interoperability. The contractor has delivered specialized plastic components to the Department of Defense, specifically supporting shipbuilding and repair efforts for T-AKE class logistics vessels. This engagement reflects a focused relationship with naval engineering teams requiring non-metallic, low-maintenance solutions for fluid systems where weight reduction and chemical resistance are paramount. Harrington’s industry focus is squarely on shipbuilding and repair (NAICS 336611), where they serve as a niche supplier of engineered polymer components that complement traditional metal-based naval hardware. Their market positioning is that of a specialized fabricator for maritime fluid systems, filling a gap in the supply chain for durable, non-corrosive alternatives in vessel maintenance and modernization programs. As a small business structured under the 2K classification, Harrington Industrial Plastics operates from Seattle, Washington, with no federal certifications on record. Their geographic proximity to Pacific Fleet support infrastructure positions them to respond rapidly to naval maintenance and repair cycles, reinforcing their role as a regional supplier within the defense industrial base.
