Industrial & Food Grade Gas Cylinder Connector | OEM Solutions for US Buyers
A gas cylinder connector is the critical safety and performance interface between your gas supply and your equipment. Whether you are sourcing for N₂O cream chargers, beverage-grade CO₂ systems, or medical oxygen, an incompatible or substandard connector leads to hazardous leaks, production downtime, and customs compliance rejections. As a specialized Chinese manufacturer with 10 years of expertise in specialty gases and equipment, we engineer high-precision gas cylinder connectors that conform to US thread standards (NPT/CGA) and international safety certifications. Our direct factory model offers OEM/ODM flexibility, competitive pricing, and reliable lead times for import managers, brand owners, and wholesalers.
The Sourcing Challenge: Why Connector Quality Matters
✕ Common Pain Points in Connector Sourcing
- Thread mismatches (BSP vs NPT) causing gas leaks.
- Substandard brass or stainless steel leading to rapid corrosion.
- Lack of FDA or ASME documentation blocking import customs.
- Inconsistent machining resulting in a poor regulator seal.
- High MOQs and slow lead times that strain your inventory cash flow.
✓ Our Engineered Solutions
- CNC precision machining to ASME / ANSI standards.
- Virgin brass bar and 304/316 SS with full material traceability.
- ISO 9001, FDA, and CE compliance documentation ready for inspection.
- 100% helium leak test and torque test on every batch.
- Flexible MOQ from 100 pcs; FOB / CIF delivery in 15–25 days.

Compliance & Rigorous Testing Protocols
In the B2B gas equipment market, trust is built on verifiable quality and regulatory compliance. Our gas cylinder connectors are manufactured in an ISO 9001 certified facility with strict process control, ensuring every unit meets the performance requirements of the US and EU markets.
ISO 9001:2015 Certified
Consistent quality management from raw material to packaging.
100% Helium Leak Testing
Guarantees zero gas migration, even under 3,000 PSI.
FDA & Food Grade Compliance
Certified materials for N₂O and CO₂ food & beverage applications.
Important Compliance Note: While our manufacturing standards align with ASME, DOT, and FDA requirements for cylinder connections, it is the buyer’s responsibility to verify final compliance with local regulations (e.g., OSHA, DOT 3AL) for the specific gas type and end-use. We provide full material certification (mill test reports) and process documentation to support your compliance audits.
Strong Factory Backing & OEM/ODM Customization
Zhuzhou XingYe Chemical Co., Ltd is not a trading company. We are a professional manufacturer with over 10 years of industry expertise, a dedicated R&D team, and a production facility spanning 8,000+ square meters. Our core specialization in specialty gases – from N₂O cream chargers to diving oxygen and ethylene – gives us a unique engineering advantage when designing gas cylinder connectors that perform reliably under extreme conditions.
Factory workshop & assembly line (8,000+ sqm facility)
What Our OEM/ODM Service Includes:
- Custom Threads: We can machine NPT, BSP, BSPT, JIS, and metric threads based on your target market requirements.
- Branding & Packaging: Laser engraving, pad printing, blister packs, or private label boxes with your logo.
- Design Adaptation: If your filling machine uses a proprietary interface, our engineers can design a bespoke gas cylinder connector to match.
- Flexible MOQ: Start with 100 pcs for standard types; scale to 10,000+ units for contract orders.
- Global Logistics: FOB Shanghai / Ningbo, CIF to major US ports (Los Angeles, Houston), or DDP for experienced buyers. We handle all export documentation.
China Supply Chain Advantage: By sourcing directly from us, you bypass multiple intermediaries. Our integrated production of both gases and equipment allows us to optimize the connector for real-world filling scenarios – reducing your logistics costs and ensuring component compatibility.
Real-World Application Scenarios
Different gas systems require specific connector configurations. Here is how our solutions address common industry needs:
🍦 Cream Charger Filling
High-speed filling of 8g to 2000g N₂O tanks demands a connector with absolute seal integrity. Our CGA 320 connector is precision-machined to prevent gas loss during rapid cycling.
🍺 Beverage Carbonation
For CO₂ draft beer systems, any contaminant ruins the batch. Our 316 SS CGA 580 connector is FDA compliant and engineered for corrosion resistance in wet environments.
🤿 Diving Oxygen Supply
Oxygen service requires "oxygen-clean" components. We offer a specialized cleaning process for our CGA 540 connectors, removing all hydrocarbons to prevent combustion risks.
