DK-Lok Enters KAI Fighter Jet Fittings Supply Chain, Secures 16 Billion Won in Long-Term Orders

[Financial News]  DK-Lok, a specialist in fittings and valves, has secured long-term supply volumes of aerospace fittings for major fixed-wing aircraft produced by Korea Aerospace Industries (KAI). As the company moves into KAI's supply chain based on high-value-added aerospace fittings that it has localized, market attention is turning to whether its aerospace and defense businesses can emerge as a new growth engine.
On the 26th, DK-Lok signed a memorandum of understanding with KAI for the long-term supply of aerospace fittings worth about 16 billion won. The amount is equivalent to about 12.4% of last year's revenue of 128.8 billion won. The actual purchase volume and timing will be finalized later, depending on KAI's production plans.
The MOU covers aerospace fittings used in KAI's flagship fixed-wing aircraft, including the KAI KF-21 Boramae, FA-50 and TA-50. The company plans to supply the related volumes through 2030, and says the deal is meaningful because it secures a stable long-term revenue base in aerospace and defense.
In particular, the 'External Swaging' and 'Beam Seal' type fittings in the supply list are advanced components used in aircraft fluid systems. They require strict quality control, traceability and certification, making them a market with higher barriers to entry and greater added value than ordinary industrial fittings.
To improve cost competitiveness and delivery responsiveness for aerospace fittings, DK-Lok has internalized its manufacturing process from testing to production. It became the first company in the domestic industry to obtain Nadcap Fluid Distribution System certification and has also built its own aerospace fitting testing facilities. It is also seeking ISO/IEC 17025 and KOLAS certification within this year.
Industry observers say the supply could offer further growth potential if it aligns with KAI's expansion in aircraft exports. As production of the KF-21 and FA-50 increases, new installation volumes are also likely to rise. In addition, aircraft characteristics mean demand for replacement parts could continue over the long term during maintenance, repair, and overhaul (MRO).
The company is also pursuing overseas expansion. DK-Lok has signed non-disclosure agreements (NDAs) with global commercial and military aircraft manufacturers and is in talks to supply its products. Its strategy is to use its supply record with KAI and international certifications as references to expand into the global aerospace fittings market.
An industry official said, "Aerospace parts are a market where certification and delivery history themselves act as barriers to entry for new companies." The official added, "The fact that the company has entered the long-term supply chain for mass-produced aircraft after localization is significant, as it gives DK-Lok a reference point that could help it expand to other aircraft platforms and overseas customers."
CEO Noh Eun-sik said, "Aerospace components have higher added value than general industrial products, so we also expect profitability to improve as related sales grow." He added, "We will continue expanding our position as a global aerospace parts company."
