Product 2: YIYADECO 6.8L DOT Carbon Fiber Cylinder
Capacity: 6.8 liters / 416 cubic inches. Working pressure: 4500 psi. This DOT-approved carbon fiber tank is designed for reliability in airgun systems and is suitable for use in both field and range settings where certification matters for transport and filling operations.
Product 3: TUXING 4500psi 6.8L Carbon Fiber Tank
Capacity: 6.8 L. Service pressure: 3000-4500 psi. Thread: M18x1.5. Certification: CE (Not DOT). Construction uses AL6061 liner with carbon and glass fiber winding. Hydrostatic test pressure up to 50 MPa; minimum burst pressure up to 102 MPa. Designed for PCP rifles and similar air systems seeking a larger reservoir with robust safety margins.
Product 4: IORMAN 3L 4500psi Carbon Fiber Air Tank
Capacity: 3 liters. Working pressure: 3000-4500 psi. CE certified. Not DOT. Thread: M18x1.5. The tank is designed for PCP paintball and scuba-style air systems, offering a balance between capacity and portability for shooters who need a mid-sized cylinder with reliable lifecycle data.
Product 5: Pautaca DOT 98ci 4500Psi Carbon Fiber Tank
Capacity: 98 cubic inches (about 1.6 gallons). Working pressure: 4500 psi. Certification: DOT and CE. Bottle neck thread: 5/8-18UNF. Length around 10.43 inches. Inspected every 5 years with a stated service life of up to several years. Equipped with dual gauge inflation valve for precise monitoring during fill and use, making it a practical choice for portability and quick refills in the field.
Buying Guide: Key Purchase Considerations
- Certification and safety: Look for CE and/or DOT certifications, hydrostatic and minimum burst pressure ratings, and defined inspection cycles to ensure safety and compliance with local regulations.
- Capacity and pressure: Match tank capacity with intended use (compact for portability vs. larger capacity for extended sessions). Consider working pressure (30 MPa / 4500 psi is common) and the recommended service range for your rifle or fill station.
- Thread compatibility: Verify neck threads (most common: M18x1.5) to ensure a proper fit with your fill system, regulator, and rifle quick-connects.
- Materials and construction: Carbon fiber winding and aluminum liners provide strength with light weight. A protective epoxy coat and corrosion resistance extend service life in harsh environments.
- Lifecycle and maintenance: Check inspection cycles (3 years is common) and overall service life estimates. Consider whether the cylinder requires professional re-certification or re-fill services at regular intervals.
- Portability vs. reliability: Smaller tanks offer easier transport but less air per fill; larger tanks reduce recharges but may be heavier. Choose based on field needs, range time, and transport constraints.
- Fill ecosystem: Ensure compatibility with your fill station and regulator setup. Some tanks include dual gauges or integrated valves for easier monitoring during fills.
