OIL FILTER SERVICE, INC.

OIL FILTER SERVICE, INC. specializes in the manufacturing of precision fabricated wire components, particularly connecting rod pins and related fastening hardware for defense applications. Their technical expertise lies in high-integrity metal fabrication, including cold heading, swaging, and precision machining of wire stock to meet stringent military specifications. The company delivers mission-critical fasteners used in engine and powertrain systems, where dimensional accuracy, material consistency, and fatigue resistance are essential. Their capability centers on small-batch, high-reliability production of custom wire-formed parts, with an emphasis on meeting AS9100 and MIL-SPEC requirements without formal certification, suggesting a focus on niche, low-volume defense supply chains. The contractor’s primary agency relationship is with the Department of Defense, where they supply specialized wire components for mechanical assemblies in ground and possibly naval vehicle systems. Their work supports maintenance, repair, and overhaul (MRO) operations, indicating a role in sustaining legacy platforms through replacement part manufacturing. This suggests a trusted, long-term supplier relationship focused on technical reproducibility rather than large-scale production. Their core industry focus is in NAICS 332618—Other Fabricated Wire Product Manufacturing—encompassing the transformation of wire into engineered components such as pins, clips, and retainers. This vertical specialization positions them within the defense industrial base as a tiered supplier of small but mission-essential hardware, often used in high-stress mechanical environments. They operate in a highly specialized segment where design fidelity and material traceability outweigh volume. OIL FILTER SERVICE, INC. is structured as a small, privately held entity (ZZ classification) based in San Diego, California. While they hold no formal government certifications, their ability to secure DoD contracts implies adherence to quality control standards required for defense supply. Their geographic location supports proximity to major defense contractors and naval facilities in Southern California, reinforcing their role as a regional supplier of precision wire components for military applications.
