Marinex

What Marinex does

Marinex, Inc. is a privately held B2B supplier of automotive and hydraulic parts for military and commercial sectors, founded in 1984 and headquartered in Brea, California. The company distributes and supplies military-grade transmissions and drivetrain components, most notably holding exclusive global distribution rights from Allison Transmission for the XTG411 transmission family and its parts, with Allison directing its vendors to supply Marinex directly. Marinex also supplies defense hydraulic components, hydrostatic pumps and motors, servo actuators, valves, and ammunition conveying equipment into platforms such as the M109A2 Self-propelled Howitzer, M113 APC, and K9 Self-propelled Howitzer through channel partners S&T Dynamics (Korean Army) and Allison Transmission (US Army).

The company's product portfolio spans defense parts, powder-metal automotive components (valve seats, valve guides, connecting rods, rotors, hub synchronizers, transmission gears and housings), and mobile and industrial hydraulic systems (piston pumps, swing devices, travel devices, sectional control valves). Adjacent offerings include patented servo actuators (SG SERVO), pitch control valves for marine propellers, flow control valves for NIKE missiles and injection molding machines, and steering cylinders for Maglev trains. Marinex operates a wholly owned holding structure with four subsidiaries: Marinex Korea, Inc. (regional operations in South Korea since 2005), Marinex Global Inc. (internet sales, LED lamps, medical equipment trading), Marinex Logistics (forwarding, trans-loading, transportation, storage), and a Consulting arm focused on Korea offset services and market development.

Marinex makes money primarily through one-time parts sales (defense parts trading, commercial automotive components, hydraulic systems) and a smaller stream of professional services revenue from Korea Offset Services for DAPA, contract manufacturing/OEM qualification, and US Export/Import compliance consulting. Pricing is quote-based B2B with no public disclosure. The go-to-market is enterprise field sales supplemented by channel partnerships with Allison Transmission (global, exclusive for XTG411) and S&T Dynamics (Korean defense), with direct engagement with US Army and Korean Army end customers. Marinex also leverages its decades-long DAPA relationships to act as a regulatory intermediary helping US companies negotiate MOAs and MOUs under Korea Offset Guidelines.
