Leak Testing

Leak Testing Solutions

Precision-engineered systems for guaranteed integrity.

At Incotech, we design and manufacture bespoke leak testing machines and fixtures for a wide range of components and assemblies. Built around proven, industry-standard principles and enhanced with advanced automation, our systems deliver repeatable accuracy, reliability, and efficiency in even the most demanding production environments.

Our most commonly used technique, the pressure decay method, works by pressurising the component with low-pressure compressed air, isolating it, and monitoring any pressure loss over time. By comparing the results to precise test parameters, the system determines whether a component passes or fails — giving manufacturers total confidence in the integrity and performance of their products.

Intelligent Automation

Every leak test system can be designed as a fully automated solution, complete with:

• Custom fixtures to securely hold and clamp the component

• Actuated sealing devices to close off openings or ports

• Integrated safety enclosures for operator protection

• Automated pass/fail indication, data capture, or part marking for traceability

Our control systems integrate seamlessly with existing production lines, offering fast cycle times, minimal operator input, and consistent results.

Versatile Test Media

Depending on application requirements, we can employ a range of test media — including air, water, oil, nitrogen, or helium — to achieve the required accuracy and sensitivity. Each solution is carefully engineered to suit the product’s geometry, materials, and pressure conditions.

Manual and Offline Testing

For smaller-scale operations or R&D environments, Incotech also design and build manual leak testing instruments. These standalone units provide a robust and user-friendly way to test individual components offline, offering the same attention to detail and measurement precision as our fully automated systems.

Whether it’s a single-station manual tester or a complex, multi-channel automated rig, Incotech’s leak testing solutions are built to ensure quality, reliability, and repeatability — every time.
