It is essential to acknowledge that every object in this world has some degree of leakage, but the key factor is whether it remains within acceptable limits. 

Leak testing is crucial because

• Safety: Ensures that it detects and prevents hazardous gas leaks or entry of contaminants into your test piece or system.
• Quality Control: To ensure that your test part is meeting the quality standards and regulatory requirements.
• Environmental Protection: To ensure that your test piece is leakproof and does not pollute or contaminate the surrounding environment.
• Improved product lifespan: To improve your product lifespan by restricting entry of contaminants or restricting wear and tear and damage due to continuous leaks.
