AUSCO

What AUSCO does

AUSCO is a 68-year-old, privately held precision manufacturer (incorporated 1957) of miniature fluid control components and systems for high-value, performance-critical applications. Operating from an 85,000 sq ft single-site facility in Farmingdale, New York, the company designs, manufactures, and tests check valves, relief valves, pressure regulators, shuttle valves, solenoid valves, combination valves, manifolds, and hydraulic systems with tolerances in the millionths of an inch. Its technology stack rests on multi-axis CNC machining (Swiss CNC, 5-axis mills), 100% in-house product testing across multiple fluid media (Skydrol, hydraulic oils, lube oils, fuel, coolants, water), and engineering simulation using SolidWorks, ANSYS, and proprietary electromagnetics tools. The patented Uni-Body Insert Relief Valve exemplifies its approach of consolidating multiple fluid functions into a single package with fewer parts and tighter leakage control.

The company earns revenue through a mix of hardware sales and engineering services. Core product lines include Build-to-Specification custom valves, Standard Plus off-the-shelf miniature valves, and integrated Manifold solutions. Service revenues come from Custom Design, Build-to-Print manufacturing, Development & Qualification Testing (ATP/QTP/QTR), Source Approval Requests (SARs) for defense procurement, long-term Spare Parts support (including legacy/sunset parts), and Reverse Engineering for obsolete products. AUSCO sells B2B through direct enterprise field sales and engineering-driven engagement, targeting tier-1 aerospace and defense OEMs (Lockheed Martin, Raytheon Technologies, aircraft engine manufacturers) as well as oil & gas tool providers. Its certifications — AS9100 (since 2004), Nadcap with 24-month merit status, FAA-PMA 14CFR Part 21 approval, and ISO 9001 — underpin qualification into these customer programs.

AUSCO's customer base is concentrated in U.S. defense and commercial aerospace, with multi-decade relationships anchoring revenue. The company is owned by holding company GWP Inc., has 101–250 employees, and has not disclosed external funding rounds, indicating a history of organic, privately financed growth. Recent operational signals include a new CFO (2024), certification renewals through 2026–2028, and planned participation in the Farnborough International Airshow 2026, suggesting measured expansion without a visible growth-stage capital event.
