What Heco International does

Heco International A/S is a Danish private limited company founded in 1959, headquartered in Hedensted, Denmark, and a wholly-owned subsidiary of G&O Maritime Group within its Propulsion Management division. The company designs, manufactures, and supplies piston rod stuffing boxes and scraper rings specifically for two-stroke marine diesel engines. Its products prevent oil and fuel leakage around the piston rod as it moves through the engine block and are continuously engineered to accommodate emerging alternative fuel types (methanol, ammonia, LNG) in support of the maritime industry's decarbonization transition.

Heco generates revenue through two streams: OEM supply of stuffing boxes to engine manufacturers and shipyards for new vessel construction, and aftermarket spare parts supply to ship owners and operators maintaining the global two-stroke engine fleet. The company operates a sales-led, contact-based direct distribution model from its Danish headquarters, reaching customers worldwide through phone and email inquiries, supplemented by digital marketing via its corporate website, LinkedIn presence, and G&O Maritime Group cross-promotion.

The company is privately held under the G&O Maritime Group conglomerate, which since 2015 has encompassed multiple maritime technology brands including HJ Lubricators, G&O Compensators, Pres-Vac Engineering, G&O Bioreactors, Atlas Incinerators, and Global Boiler Services. Ownership beyond the parent group is not disclosed, and no public listing exists. No revenue, headcount, or pricing data is publicly available.
