The Leak Testing Market is projected to surpass USD 14.7 billion by 2035, rising from an estimated USD 9.3 billion in 2025. This growth reflects a CAGR of 4.7% between 2025 and 2035.
Adoption of non-destructive and high-precision leak testing methods has been accelerated across sectors such as automotive manufacturing, pharmaceutical packaging, and HVAC system validation. This shift has been shaped by increasingly stringent quality regulations and evolving global safety mandates.
In January 2024, an Automatic Glove Leak Testing System was introduced by Tema Sinergie to enhance integrity assurance in high-containment isolators used within pharmaceutical cleanrooms. According to Cleanroom Technology, the automation of this process was designed to reduce human error and inspection fatigue, thereby improving compliance with Annex 1 requirements. The system was aligned with rising demand for consistent leak detection performance in sterile and highly regulated environments.
As highlighted in a 2024 technical brief by Uson, pressure decay and helium mass spectrometry methods have remained dominant in precision leak testing. It was noted that microscopic leaks-often undetectable through traditional immersion techniques-have been increasingly identified using helium-based detection. Although considered capital-intensive, these systems have been widely deployed in powertrain assembly lines and critical-care medical devices due to their traceability and ultra-high sensitivity.

Detectors are projected to dominate the global leak testing machine market, accounting for approximately 52% of total revenue in 2025. Over the forecast period from 2025 to 2035, the detector segment is expected to grow at a CAGR of 4.9%, slightly above the global industry growth rate of 4.7%. Their widespread use in pressure-based and gas-based leak detection across manufacturing, energy, and utilities sectors makes detectors the cornerstone of leak testing operations.
Among the detector subtypes, pressure decay leak testing systems are the most commonly deployed due to their cost-effectiveness, ease of integration, and suitability for high-volume production lines. Meanwhile, tracer gas and vacuum decay systems are preferred in high-sensitivity applications, particularly in aerospace, refrigeration, and battery production, where even micro-leaks can lead to system failure.
Technological advancements such as automated calibration, real-time data acquisition, and integration with industrial control systems (PLC/SCADA) are further enhancing detector performance and diagnostic accuracy.
Oil & gas refineries are expected to remain the largest end-use segment in the leak testing machine market, contributing approximately 28% of global revenue in 2025, with the segment forecast to grow at a CAGR of 5.0% through 2035. The sector’s stringent safety and environmental standards require routine and high-accuracy leak detection across pipelines, valves, pressure vessels, heat exchangers, and storage tanks.
Leak testing systems are being adopted both during plant commissioning and in ongoing maintenance schedules to prevent hazardous emissions and comply with regulations such as LDAR (Leak Detection and Repair) programs. Tracer gas methods and mass flow test systems are particularly prominent in detecting fugitive emissions in complex refining networks.
Additionally, the integration of digital sensors and portable diagnostic tools is supporting on-site testing efficiency and reducing downtime. With global investments rising in refinery expansions and upgrades-especially in the Middle East, Asia-Pacific, and North America-demand for robust and automated leak detection systems is projected to steadily increase over the next decade.
Growth in Modular and Customizable Solutions
Stringent regulations in the form of global safety and environmental regulations, especially among industries like oil & gas refineries, power plants, and chemical facilities, are the main drivers for leak testing machines.
Laws have been passed by governments and regulatory bodies to tightly enforce emissions and leakages to prevent potential threats of environmental hazards and ensure workers' safety. In industries dealing with hazardous materials and gases in the chemical processing of materials, spillage and possible explosions cannot be overlooked in leakage detection.
To avoid environmental pollution, companies engaged in petroleum production have adopted more stringent requirements regarding LDAR as established by the USA Environmental Protection Agency. As such, the increase in these regulations is likely to fuel the need for highly sensitive and accurate test equipment, for instance, gas-based and pressure decay leak test equipment. Thus, this regulation, although being a challenge to the market growth, is, on the other hand, the largest driver in high-risk applications.
Technological Advancements in Leak Testing Equipment
The technological advancements are primarily responsible for the growth in leak testing machines. Advanced detection methods, such as gas-based leak testing: helium and hydrogen-based leak testing methods, have significantly changed the very nature of leak detection. This significantly increases precision in big automotive manufacturing, HVAC, and electronics. Hence, IoT-enabled leak testing systems help improve real-time monitoring and predictive maintenance.
Companies such as ATEQ Corporation are innovating IoT-enabled testing systems that offer remote monitoring and data analytics. This has helped minimize downtime and maintenance costs. The technological developments have improved the speed and accuracy of leak detection, and more complex systems are in demand.
In addition, the micro-leak detection and automated testing system are revolutionizing the automotive and HVAC industries. Here, a small leak may significantly affect product performance and safety. This drive towards high-tech leak detection solutions is thereby expanding the market's scope and accelerating its growth.
Growth in Demand for Automated Leak Testing Systems
There is a significant trend toward the adoption of automated leak testing machines across various industries to enhance efficiency, reduce human error, and optimize production processes. Equipped with high-quality sensors and data analytics, automated systems continue to monitor the equipment in real-time, helping identify problems well before they are too expensive. In the case of the automobile industry, it employs leak testing in the testing of car parts such as the fuel system to identify leaks; such systems are considered highly accurate.
Such automated systems not only increase the speed of testing but also reduce labor costs and improve production efficiency as a whole. In addition, integration of automated leak testing solutions with other automatic processes used in stages of production such as assembly lines in HVAC and refrigeration leads to an increased demand for more complex and efficient machines. As industries advance toward Industry 4.0, with connected devices and smart factories, the trend of automation in leak detection is expected to grow rapidly.
