The growth in the historic period can be attributed to increasing adoption of couplers to ensure secure mechanical connections in aircraft systems, early use of torque-limiting and flexible shaft couplings to protect critical drivetrain components, rising demand for reliable coupling solutions to prevent leaks during aircraft refueling, expansion of aerospace manufacturing requiring standardized coupling components, development of rigid and close-coupled designs to support high-precision power transfer.

The aerospace couplers market size is expected to see strong growth in the next few years. It will grow to $6.98 billion in 2030 at a compound annual growth rate (CAGR) of 7%. The growth in the forecast period can be attributed to growing demand for advanced coupling technologies to improve aircraft efficiency and safety, increasing integration of lightweight and high-strength materials in aerospace couplers, rising aircraft production and fleet modernization driving need for high-performance couplings, technological advancements enabling enhanced torsional vibration control in coupling systems, expansion of aerospace maintenance and retrofitting activities requiring upgraded coupling components. Major trends in the forecast period include rising adoption of torque-limiting couplers, increasing use of high-strength, lightweight materials, advancements in leak-prevention coupling technologies, growing demand for military-grade refueling couplers, expansion of aerospace power-transmission component manufacturing.

The rise in air passenger numbers is expected to propel the growth of the aerospace couplers market in the coming years. Air passengers include both domestic and international travelers transported by air carriers. Aerospace couplers, widely used in the aviation industry, play a crucial role in aircraft manufacturing. They are commonly applied in compressors, dynamometer test stands, fans, flywheels, gas turbines, gearboxes, generators, mixers, outfeed rollers, pumps, and other systems. The increasing air passenger traffic drives demand for new aircraft, thereby boosting the need for aerospace couplers. For instance, in December 2025, Eurostat, a Luxembourg-based government agency, reported that in 2023, the number of passengers transported by air increased by 19.3% compared to 2022. Therefore, the rising air passenger count is expected to fuel the growth of the aerospace couplers market.

Key players in the aerospace couplers market are focusing on leveraging advanced technologies such as sophisticated radio frequency (RF) designs to enhance performance and reliability in demanding environments. Advanced RF designs involve the engineering of components that operate at radio frequencies to optimize signal transmission, reduce losses, and efficiently handle high-frequency signals, thereby improving signal quality, increasing power efficiency, and ensuring reliable performance in critical aerospace and defense applications. For example, in May 2024, TTM Technologies Inc., a US-based manufacturer, launched its Xinger high-performance 50W directional and hybrid couplers for X-Band (8-12 GHz) commercial-off-the-shelf military and aerospace applications. These ultra-compact 5 mm x 3.2 mm surface-mount components are designed for essential functions such as power and frequency detection, voltage standing wave ratio (VSWR) monitoring, and power splitting and combining. Featuring a peak-to-average ratio of 12 dB, an average power rating of 50 W, and an electroless nickel immersion gold (ENIG) finish for enhanced reliability, these couplers demonstrate the application of advanced RF designs to ensure high performance in harsh operational conditions.

In May 2024, Amphenol Corporation, a US-based manufacturer, acquired Carlisle Interconnect Technologies, Inc. (CIT) from Carlisle Companies Incorporated for an undisclosed sum. Through this acquisition, Amphenol Corporation aims to strengthen its offerings in highly engineered harsh environment interconnect solutions, expand its technology portfolio for clients in the commercial air, defense, and industrial sectors, and leverage CIT’s skilled workforce to improve operational performance. Carlisle Interconnect Technologies, Inc., based in the US, specializes in manufacturing aerospace couplers.
