Wholesale 4.0L Carbon Steel Cylinder – Reliable Bulk Supply for Industrial & Food‑Grade Gases
If you’re sourcing a wholesale 4.0L carbon steel cylinder for N₂O, CO₂, or other compressed gases, you need a partner who guarantees consistent quality, competitive pricing, and on‑time delivery. As a factory‑direct supplier with over 10 years of experience, Zhuzhou XingYe Chemical offers certified stainless‑steel cylinders that meet US DOT and international UN standards. Whether you are an import manager, brand owner, or wholesaler, our OEM/ODM capabilities and fast lead times help you maintain supply chain efficiency without compromising safety or compliance.
Common Challenges in Bulk Cylinder Procurement
Buyers often face three major pain points when sourcing high‑pressure cylinders from overseas:
- Inconsistent quality – variations in wall thickness, valve threads, or hydrostatic test results.
- Long lead times – some factories quote 60–90 days, disrupting your inventory planning.
- Hidden certification gaps – cylinders that claim “ISO 9001” but lack DOT or UN 1044 approval.
Our 4.0L carbon steel cylinders address each of these concerns through factory‑controlled production, strict third‑party testing, and a streamlined supply chain.

Application-Guided Performance
The 4.0L carbon steel cylinder is ideal for:
- Whipped cream / N₂O chargers – widely used in restaurants and dessert chains.
- Beverage carbonation – CO₂ cylinders for soda fountains or draft beer systems.
- Medical oxygen – portable O₂ cylinders for emergency services.
- Diving – compact pony bottles for scuba tanks.
Compared to aluminum cylinders of the same volume, carbon steel offers higher pressure ratings and lower cost per unit – a critical advantage for large‑scale wholesalers.
| Feature | Carbon Steel 4.0L (Our Cylinder) | Typical Aluminum 4.0L |
|---|---|---|
| Service Pressure | 200 bar | 150 bar |
| Weight (empty) | 6.5 kg | 5.0 kg |
| Cost per piece (at MOQ 500) | $11.50 – $13.80 (FOB) | $15.20 – $18.00 (FOB) |
| Hydrostatic test lifespan | 5 years (DOT compliant retest) | 5 years |
| Lead time for custom logo | 30–35 days | 45–60 days (common) |

What Our Bulk Buyers Say
Import Manager – Midwest Gas Supply, USA
“We’ve been sourcing 4.0L cylinders from Zhuzhou XingYe for two years. The DOT compliance is spot‑on, and their lead time consistently beats our previous supplier by two weeks. The hydrostatic test report is always attached – no surprises at customs.”
Owner – CoolWhip Brands, Canada
“I needed a private‑label cylinder for my N₂O charger line. They created a custom valve thread and painted the cylinders with my branding in under 35 days. The final product had zero pinholes, and the valve seal held beautifully. Highly recommended for OEM projects.”

Wholesale Director – Pacific Gas Solutions, Australia
“Switched to XingYe after a disappointing batch from another Chinese factory. Their carbon steel cylinders are consistently within 0.2 mm of the specified wall thickness. The customer service team even helped me sort out the container documentation for Australian customs.”
Sourcing Agent – Euro Industrial Gases GmbH, Germany
“I’ve audited their factory personally. The production line is clean, the welders are certified, and they maintain a separate area for hydrostatic testing. The CE mark on the cylinders is genuine – we verified it with our local notified body. A trustworthy partner.”
MD – FreshWhip Ltd., United Kingdom
“I was skeptical about the price because it was lower than my previous source. We did a 100‑piece trial – all passed the valve torque test and the paint didn’t chip during shipping. Now I order 1,500 pieces every quarter. The savings add up.”
