Type 2 CNG Cylinder – Lightweight Composite Natural Gas Storage for Commercial & Industrial Fleets
A Type 2 CNG cylinder combines a seamless steel or aluminium liner with a carbon-fibre or glass-fibre composite wrap, delivering a pressure rating of up to 250 bar at approximately 30–40 % lower weight than a fully steel cylinder. Ideal for heavy-duty trucks, buses, light-commercial vehicles, and stationary gas storage, this cylinder type meets ISO 11439, ECE R110, and DOT FMVSS 304 standards. Below we examine its construction, compliance requirements, sourcing considerations, and how our factory supports import managers, brand owners, wholesalers, and sourcing agents with reliable supply and customisation.
Why the Type 2 CNG Cylinder Matters for Your Procurement Portfolio
For import managers and sourcing agents evaluating composite CNG cylinders, the central questions are always: safety certification, lifecycle cost, and supply reliability. A Type 2 cylinder offers a proven middle ground between a full-steel Type 1 (heavy, lowest cost) and a full-composite Type 3/4 (lightest, highest cost). The metal liner provides robust gas barrier properties, while the composite hoop wrap reduces overall weight by approximately one-third, making it easier to install in space-constrained vehicle chassis.
However, inconsistent quality from unaudited factories, long lead times, and incomplete certification packages remain major pain points. Our operation addresses each of these through ISO 9001-controlled production, batch traceability, and dedicated logistics coordination for North American and European buyers.

- Monthly output: up to 4,000 units (various sizes from 30 L to 140 L water capacity).
- Workforce: 120 skilled operators and 14 quality-control engineers.
- Standard MOQ: 50 units per size. Lower MOQs available for sampling or pilot projects (subject to negotiation).
- Lead time: 25–35 days for standard orders; 15–20 days for repeat orders with confirmed material stock.
- Customisation: OEM/ODM – valve threads (M22×1.5, G½, etc.), external coating colour, laser marking, barcode/QR labelling, and packaging design.
Compliance & Certification – No Shortcuts

Every Type 2 CNG cylinder we supply is tested to the applicable standard based on the destination market. Our certification portfolio includes:
For each shipment we provide a Certificate of Conformity (COA), test reports for burst pressure, leak tightness, and fatigue cycle. Third-party inspection (SGS, BV, or Intertek) can be arranged at buyer’s cost. Our quality system tracks every cylinder via a unique serial number stamped on the shoulder.
Note: Certification scope may vary by cylinder size and destination. Please confirm your specific compliance requirements with our sales team before placing a formal order.
Where Type 2 CNG Cylinders Deliver the Best ROI
Heavy-Duty Trucks
Typical 8-cylinder pack (8×80 L Type 2) saves ~240 kg vs. all-steel, increasing payload without sacrificing range.
Transit & School Buses
Roof- or underfloor-mounted banks. Lightweight reduces suspension stress and improves fuel economy.
Stationary Storage
Buffering for CNG fuelling stations. Type 2 offers a cost-effective solution where weight is less critical than cycle life.
Light-Commercial Vehicles
Vans and small trucks benefit from the 30 % weight reduction while keeping acquisition cost lower than full-composite.
OEM/ODM Design – Your Brand, Your Specification
Brand owners and distributors often require a cylinder that reflects their identity or meets a niche application. Our OEM/ODM service covers:
- Valve interface: M22×1.5, G½, G¾, or customer-specified thread.
- External finish: RAL colour paint, powder coating, or bare composite with clear coat.
- Marking & labelling: Laser-engraved or embossed logo, pressure rating, serial number, barcode, and QR code linking to your product page.
- Packaging: Individual polybag + wooden pallet/crate, or bulk shrink-wrapped unit loads. Export cartons can be printed with your artwork.
- Documentation: COA, MSDS (if applicable), certification copies, and packing list in your language (English, Spanish, French, Arabic).
We maintain strict confidentiality agreements – your design and sourcing data remain protected.
What Global Buyers Say About Our Type 2 CNG Cylinders
Fleet Manager, Midwest USA
“We replaced 120 steel cylinders with Type 2 from XingYe. Weight savings allowed us to add one extra cylinder per truck without exceeding axle limits. Certification paperwork was complete and accepted by DOT. Lead time was 31 days – met our deadline. Will reorder.”
Sourcing Agent, Dubai
“I sourced Type 2 cylinders for a bus fleet project in Saudi Arabia. The factory provided OEM marking with our logo and Arabic labelling without extra charge. Quality was consistent across the 300-unit order. Communication was clear and responsive.”
Procurement Manager, Barcelona
“We compared four suppliers. XingYe had the best balance of price, delivery, and certification scope for ECE R110. The sample arrived within 12 days and passed our internal burst test. We have placed two follow-up orders since.”
