When Is CNG Cylinder Hydro Testing Mandatory?

CNG cylinder hydro testing is a **mandatory safety procedure** required under Indian government regulations to ensure that compressed natural gas cylinders remain safe for use. In Gurgaon and across India, vehicle owners must comply with these testing norms to avoid penalties and safety risks.

🔹 What Is Hydro Testing?

Hydro testing involves filling the CNG cylinder with water and pressurizing it beyond normal operating limits to check for leaks, deformation, or structural weakness. Water is used instead of gas to eliminate explosion risks.

🔹 When Is Hydro Testing Required?

• Every 3 years from the date of last test
• After any accident or cylinder damage
• When refilling stations reject the cylinder
• Before reinstallation in a new vehicle

🔹 Legal Requirement in Gurgaon

As per PESO (Petroleum and Explosives Safety Organization) guidelines, driving with an expired CNG cylinder test is illegal. Vehicles without valid hydro test certification may face:

• Heavy fines
• Fuel station rejection
• Vehicle insurance issues
• Serious safety hazards

🔹 Where to Get CNG Cylinder Hydro Testing in Gurgaon?

Always choose a government-approved CNG cylinder hydro testing centre in Gurgaon to ensure accurate testing, proper stamping, and official certification.

Why CNG Leakage Testing Is Critical for Vehicle Safety

CNG leakage testing is one of the most important safety checks for CNG-fitted vehicles. Even a small gas leak can lead to fire hazards, engine malfunction, or life-threatening accidents.

🔹 What Causes CNG Gas Leakage?

• Loose valves or connectors
• Damaged pipelines
• Worn-out O-rings
• Improper installation
• Expired cylinders

🔹 Signs of CNG Leakage

• Strong gas smell inside or outside the vehicle
• Hissing sound near the cylinder
• Sudden drop in fuel efficiency
• Difficulty starting the engine

🔹 How Leakage Testing Is Done

At a certified CNG testing centre in Gurgaon, leakage testing is performed using pressure checks, soap solution tests, and specialized detection equipment to ensure complete safety.

🔹 Why Choose a Government Approved Centre?

Only approved testing centres provide authentic leakage inspection reports that are accepted by fuel stations, transport authorities, and insurance companies.

🔹 Stay Safe on Gurgaon Roads

Regular leakage testing not only ensures legal compliance but also protects passengers, vehicles, and surrounding traffic. Never ignore early warning signs.
