Ultrasonic Testing	Use sound waves to detect internal flaws that are not visible, allowing for early intervention.

When you test the connection, apply pressure gradually and observe for any signs of leakage. This step ensures you catch issues that may not appear during a static inspection.

Common mistakes during visual inspection can compromise your ability to detect leaks. The table below highlights frequent errors and their impact:

Mistake Description	Impact on Inspection
Firesleeve cut too short	Exposes fitting, compromising fire rating.
Nut and nipple assembly not fully screwed	Excessive gap leads to non-airworthy hoses.
Rubber flap cut into hose inner tube	Can cause inner-liner damage, affecting functionality.
Socket backed out during assembly	Risk of the fitting blowing off, leading to failure.
Not pressure testing the hose	First test during use can lead to catastrophic failure.
Socket turned too far during installation	Ruins hose, leading to failure under pressure.
Collapsed inner tube from improper assembly	Excessive friction can tear the inner liner, ruining the hose.

Common Leak Points

You will often find leaks at specific points in the hose assembly supply. Understanding these areas helps you target inspections and repairs more effectively. The table below summarizes the most frequent leak points in industrial applications:

Leak Point	Description
Mechanical loads	Includes vibration, tensile, and shear forces that stress the connection.
