CNG/ Helium Leak test system

Pneumatics and Hydraulics Testing Machine

Leak testing is a critical quality control process used to detect and measure leaks in products, components, or systems. Its primary objective is to verify that the tested item does not have any unintended pathways through which gases or liquids could escape or enter. Ensuring leak-tightness is essential for maintaining the reliability, safety, and performance of the product throughout its lifecycle.

This method is widely applied across industries such as automotive, aerospace, electronics, medical devices, HVAC, and packaging. In these sectors, even the smallest leak can lead to performance degradation, safety hazards, regulatory noncompliance, or significant economic losses. For instance, in the automotive industry, leak testing helps ensure that fuel systems, air conditioning units, and brake lines are properly sealed. In the medical field, it ensures the sterility and integrity of surgical instruments and fluid delivery systems.

Leak testing techniques can include pressure decay, vacuum decay, mass spectrometry, helium sniffing, bubble testing, and others—each selected based on the sensitivity, application, and materials involved. These methods help identify manufacturing defects such as cracks, porous materials, weak welds or seals, and improper fittings.

By incorporating our leak testing system into the production process, manufacturers can guarantee that their products meet industry standards, enhance customer satisfaction, reduce warranty claims, and uphold brand reputation.
