At what pressure should the LPG fuel supply line and fittings be tested?

Testing the LPG fuel supply line and fittings at 34.5 kPa is essential for ensuring the safety and reliability of the system. This pressure level is typically specified by safety standards, such as those outlined by the American Boat and Yacht Council (ABYC), which provides guidelines for the proper installation and maintenance of LPG systems on boats.

Testing at this pressure allows for the identification of any leaks or weak points in the system that could pose a risk during operation. If the system can withstand this pressure without showing any signs of leaks, it indicates that the installations are secure and reliable.

Using a pressure that is too low may not adequately test the integrity of the system, potentially allowing for undetected leaks. Conversely, testing at a pressure that is too high could potentially damage the fittings or lines, creating safety hazards. Therefore, 34.5 kPa is recognized as a balanced and effective pressure level for this critical safety test.
