Aluminum cam lock fittings require pressure testing

1. New factory connectors must be tested
Pre delivery inspection: Regular manufacturers will conduct air tightness testing (low-pressure air or water pressure) after assembly to ensure no casting defects or poor sealing.
Sampling inspection ≠ Full inspection: Some low-priced products may only be sampled, and it is recommended to test them yourself before the first use after purchase.

2. After repairing or replacing components, retesting is required
After replacing the gasket: If the new gasket (such as fluororubber) is not installed properly, it may leak pressure and needs to be retested.
After deformation repair: If the fitting is reshaped due to collision, it is necessary to test whether the sealing surface can still be compressed.

3. Daily use does not require frequent testing
Non pressure design: The cam lock is essentially a low-pressure quick release fitting designed for self flow or low-pressure pumping transportation (such as oil tank truck unloading), not high-pressure pipelines.
Visual inspection alternative: Daily observation of whether the gasket is aging and whether there is leakage after locking is sufficient, without the need for specialized pressure testing.

4. Mandatory testing for special high-risk scenarios
Chemical medium transportation: If used for hazardous liquids such as acids and alkalis, it is recommended to conduct a water pressure holding test (such as 0.5MPa, no leakage for 5 minutes) after each disassembly and assembly.
Regulatory requirements: Some industries (such as aviation fuel refueling) may require mandatory regular testing and must comply with local regulations.

5. Prohibit overpressure testing
Aluminum fittings have limited pressure capacity: Violent testing (such as using an air compressor to apply high pressure) may cause the fitting to burst or permanently deform.
Alternative method: Manually pressurize after low-pressure water injection and observe for dripping, which is safer.
