4.4L Carbon Steel Recycle Cylinder Suppliers – Safety, Compliance & Fast Global Delivery
If you are sourcing 4.4l carbon steel recycle cylinder suppliers for your next import order, you need a partner who meets US DOT/TC safety standards, offers consistent quality at scale, and supports OEM branding. Zhuzhou XingYe Chemical combines 10+ years of gas cylinder manufacturing with full certification packages, flexible MOQ, and express lead times from China’s central supply chain hub.
Why Import Managers Struggle to Find Reliable Cylinder Suppliers
Import managers, brand owners, and sourcing agents across the USA consistently face three bottlenecks when sourcing 4.4L carbon steel refillable cylinders from overseas:
- Inconsistent wall thickness and valve quality – leading to premature failure and safety liability.
- Missing or non-compliant documentation – no COA, MSDS, or DOT/TC exemption files, causing customs delays.
- Long lead times and poor communication – 60–90 day delays kill downstream production schedules.
These pain points cost buyers time, money, and reputation. A 4.4l carbon steel recycle cylinder supplier with in-house quality control, genuine certifications, and a proven export track record eliminates those risks.
Engineered for Reuse – Our 4.4L Carbon Steel Recycle Cylinders
Our 4.4L cylinders are manufactured from high-grade carbon steel (GB 18248 or equivalent ASTM A519) and designed for repeated refill cycles across multiple gas applications – N₂O cream chargers, beverage CO₂, diving oxygen, and specialty industrial gases.
Core advantages include:
- Seamless cold-drawn construction for uniform wall strength
- Heat-treated to eliminate internal stress and extend fatigue life
- 100% hydrostatic pressure test before shipment (per ISO 9809 / DOT-3AA)
- Valve options: CGA 540, CGA 320, pin-index, or customer-specified
- External finish: powder-coated blue, black, or custom RAL color

- CE (PED 2014/68/EU) – For shipments destined to or transiting European markets.
- Certificate of Analysis (COA) – Batch-specific material and test results.
- Material Safety Data Sheet (MSDS) – For safe handling and shipping documentation.
- ECM (European Conformity Module) – Additional verification for certain gas fills.
We also maintain Food-Grade Gas Certification for cylinders used in culinary N₂O and CO₂ applications – essential for cream charger and beverage dispensing end-users.
Our Factory – Where Quality Becomes Measurable

Where 4.4L Carbon Steel Recycle Cylinders Are Used
The 4.4L size is a sweet spot for portable, medium-volume gas storage. Typical applications include:
- Culinary N₂O cream chargers – refillable cylinders for whipped cream dispensers in commercial kitchens and bakeries.
- Beverage CO₂ systems – carbonation for soda fountains, home brew, and draft beer installations.
- Diving oxygen tanks – lightweight emergency O₂ supplies for dive boats and training facilities.
- Industrial specialty gases – calibration gas mixtures, welding shielding gas, and laboratory reference standards.
- Medical oxygen backup – portable oxygen supply for home care or clinical settings (with appropriate valve and purity certification).
Because the cylinder is designed for multiple refill cycles, it offers a lower total cost of ownership compared to disposable alternatives – a key consideration for brand owners and wholesalers targeting eco-conscious end users.

What Buyers Say About Our 4.4L Carbon Steel Recycle Cylinders
"We switched to XingYe after dealing with two suppliers who delivered cylinders with inconsistent valve threads. Their 4.4L units have been uniform across every batch – all 3,000 units we received passed our incoming inspection. The DOT documentation was clean, which saved us a headache with customs. Lead times have been reliable at 18–20 days."
"We needed private-label 4.4L cylinders for our N₂O cream charger line. XingYe handled everything – our logo laser-engraved, custom valve color, and retail-ready packaging. The food-grade internal cleaning was verified by our third-party lab. Response time from the sales team is under 4 hours despite the time difference."
"We source cylinders for multiple clients across the South Pacific. XingYe's factory audit report was transparent – we saw their hydrostatic test station and valve assembly line on a video call. Their MOQ of 500 units works well for our consolidated orders. The cylinders have held up well in high-humidity coastal environments."
"We run a cylinder refill program for restaurants and wanted a supplier who understands recycling. XingYe's cylinder is built for multiple cycles – we've refilled our first batch 40+ times with no signs of fatigue. The CGA 320 valve option worked perfectly with our dispensers. Shipping via CIF to Toronto was smooth."
