Why Glass Fiber Type 4 UNECE R110-Approved Cylinders Are the Perfect Choice for On-Board Vehicle Applications.

KonveGas Composites glass fiber Type 4 cylinders, made in Sweden and approved under UNECE R110, are designed specifically for on-board CNG vehicle applications, offering clear advantages over carbon fiber alternatives.

Key Advantages of Glass Fiber Type 4 Cylinders Over Carbon Fiber Cylinders

1. Higher Burst Pressure Requirement

   For the same working pressure rating, glass fiber Type 4 cylinders are required to meet a higher burst pressure threshold than carbon fiber versions. This built-in safety margin means extra protection against overpressure events, a significant benefit for vehicle applications operating under variable and demanding conditions.

2. Cost Efficiency Without Compromising Safety

   Glass fiber composites offer excellent mechanical performance at a fraction of the raw material cost of carbon fiber. This makes them a more affordable choice for manufacturers and fleet operators while still maintaining world-class safety and durability standards.

3. Durability in Real-World Conditions

   Glass fiber is highly resistant to fatigue, impact, and environmental degradation, making it ideal for vehicles operating in diverse climates and road conditions. The material’s resilience translates into long service life and lower total cost of ownership.

4. Lighter Than Metal, Strong Enough for Heavy Duty

   Glass fiber Type 4 cylinders are still significantly lighter than traditional steel or aluminum designs, improving vehicle efficiency and handling without sacrificing robustness.

UNECE R110 – Internationally Recognized Safety

Our glass fiber Type 4 cylinders meet UNECE R110 standards, ensuring:

• Rigorous burst, cycle, and leak testing

• Temperature resilience from sub-zero cold to extreme heat

• Impact and fire resistance for maximum passenger and cargo safety

This certification confirms that our products are ready for safe and compliant use in on-board vehicle CNG systems worldwide.
