What custom hydraulic & machine does

Custom Hydraulic & Machine Inc. is a privately held, single-site specialty manufacturer based in Kent, Washington, producing marine and military hydraulic hose end fittings for the US Government and naval defense market. The company has been a direct supplier to US Government production lines for more than 40 years, with its product portfolio centered on MIL-SPEC and SAE-compliant fittings (MIL-H-24135, MIL-H-24136, MIL-F-24787, SAE 100R5, SAE 100R2AT) including flange connectors, 90° dogleg fittings, O-ring seal fittings, 37° female swivel fittings, NPT male pipe thread fittings, and inner support sleeves. Core engineering capabilities include in-house SolidWorks/AutoCAD modeling, hydrostatic testing to 10,000 PSI, and operational pressure ratings up to 5,000 PSI. The company holds MIL-I-45208A quality systems certification, Level 1/Subsafe and Nuclear qualification, and NIST-800-171 cybersecurity compliance under DFARS 252.204-7012.

The business operates a direct B2B sales model with no intermediaries: customers (primarily the US Navy and US Government maritime programs) request quotes via the company website, phone, or contact form, with pricing determined per part. Distribution is domestic-only with shipping from the Kent, WA facility. Revenue is one-time hardware sales rather than recurring or licensed, and customer concentration is heavily skewed toward a single government end-buyer. The company lists Singer Industrial as a partner reference, suggesting limited distribution diversification. No public revenue, headcount, or ownership details are disclosed.
