The aircraft tube and duct assemblies market was valued at USD 1,678.9 million in 2025 and is projected to reach USD 3,938.3 million by 2035, registering a CAGR of 8.9%. This growth has been driven by the increasing demand for lightweight, corrosion-resistant assemblies in aerospace platforms. Performance requirements across modern aircraft-ranging from thermal management to pressurized fluid systems-have reshaped the material and design standards in the tubing sector.
Leggett Aerospace has confirmed its specialization in complex, high-precision bent tube assemblies for fuel, hydraulic, and environmental control systems. According to its 2024 platform documentation, assemblies are being designed using Inconel, titanium, and stainless steel alloys to support commercial, defense, and space programs. These materials have been adopted to withstand extreme pressures and temperatures, especially in supersonic aircraft and unmanned platforms.
Sustainability and vertical integration have also emerged as strategic priorities. In an interview with Investment Reports in 2024, Kai Arndt, Co-CEO of Deutsche Aircraft, stated, “By doing everything in-house, we’ve cut lead times by 80-90% and reduced the environmental impact by eliminating the need to transport parts over long distances. This vertical integration is a significant contribution to sustainability, and we apply this approach to most of the parts we produce for aircraft, from structural components to smaller assemblies”.
According to a 2025 feature in Filtration+Separation, advanced tubular ducts are increasingly being integrated with filtration systems to support bleed air purification, auxiliary cooling, and cabin pressurization in newer aircraft platforms. The synergy between duct systems and high-efficiency filters has enabled improved air quality management and performance optimization.
Increased aircraft production rates in Asia-Pacific and Europe, along with the modernization of aging military fleets, are further supporting demand for custom ducting. System-level co-engineering between OEMs and tube suppliers has become a common practice, especially for narrowbody aircraft upgrades and hybrid propulsion prototypes.
According to Airports Council International (ACI), global airport infrastructure will require over USD 2.4 trillion in investment by 2040 to meet the rising demand for air travel. As terminal expansions and new runways are developed, airlines are expected to upgrade fleets with more fuel-efficient and environmentally compliant aircraft.
These new platforms will require advanced tube and duct assemblies for optimized fluid transfer, thermal control, and air management. As a result, the anticipated fleet modernization linked to infrastructure growth will directly boost demand for next-generation aircraft tubing solutions.

Single-aisle aircraft configurations were adopted for their operational economics, contributing to sustained demand from both low-cost and legacy carriers. Procurement was further supported by regional leasing companies expanding their portfolios in anticipation of recovery-driven capacity requirements.
Titanium accounted for about 21% share in tube and duct assemblies’ market in 2025 and is projected to grow at a CAGR of 9.2% through 2035. The material was selected for its high strength-to-weight ratio and corrosion resistance, especially in fuselage structures, landing gear, and engine parts. Titanium usage increased in wide body and military aircraft platforms, where structural durability and weight optimization were prioritized.
Aerospace OEMs reported increased sourcing of forged titanium alloys for turbine blade manufacturing and load-bearing wing assemblies. Demand was also influenced by the growing penetration of titanium in additive manufacturing applications for aerospace parts. Between 2024 and 2025, supply agreements were executed between Tier-1 suppliers and raw material processors in North America and Europe to secure titanium billet and plate supply for long-term production programs.
Challenges
Manufacturing and Material Cost Stability
The components of aircraft tubes and ducts are made from the highest quality alloys, go through precision machining, and involve rigorous testing; thus, the costs are very high. The trend of using titanium, carbon-fiber composites, and nickel-based super alloys for construction adds more than a bit to the raw materials, which makes the task of cost optimization all the more difficult for manufacturers.
Besides, the need for intricate fabrication methods, strict aerospace quality standards, and regulatory compliance forces increase production costs, making it hard to accommodate small aircraft manufacturers. Companies invest in 3D printing, auto welding, and AI defect detection to minimize production costs while ensuring premium quality.
Strict Air Safety & Quality Control Rules
Ducting tubing and duct assemblies in aircraft must pass regulatory tests by organizations such as the FAA (Federal Aviation Administration), EASA (European Union Aviation Safety Agency), and ICAO (International Civil Aviation Organization). This includes the need for rigorous testing like high-pressure tolerance, heat resistance, and material fatigue durability, increasing the certification complexity, and costs.
The adherence to breaking the way environmental impact laws have mandated and the fire resistance requirement of the manufacturers to invest in sustainable materials, advanced coatings, and recyclable ducting solutions means that the R&D expenses will go up.
Opportunities
