Mandatory hydrostatic testing for your CNG vehicle cylinder as per the Gas Cylinder Rules, 2004. Fast, safe, and certified — serving Dwarka, Najafgarh, Janakpuri & surrounding areas.
Under the Gas Cylinder Rules, 2004 and PESO guidelines, every CNG vehicle cylinder must undergo hydrostatic testing every 3 years — no exceptions.
CNG cylinders operate at 200–250 bar pressure. Micro-cracks, corrosion, and metal fatigue are invisible to the naked eye but detectable through hydrostatic testing before they cause failures.
Filling stations are mandated by PESO to check test validity. An expired certificate means your vehicle cannot be refuelled until the cylinder is retested and recertified.
An untested cylinder can void your vehicle insurance policy in the event of an accident. The test certificate is a legal document required for continued road use.
Testing includes internal cleaning to remove oil build-up and moisture, which improves gas flow efficiency and can enhance your engine's performance after the test.
