AeroDry Series Dry Disconnect Coupling
The ZeroGas sseries Dry Disconnect Coupling is a specialized line of dry disconnect couplings engineered for the safe and efficient transfer of Liquefied Petroleum Gas (LPG) and similar media. Designed to connect hoses, crane pipes, loading arms, and mobile units (such as tank cars and railway tankers), the ZeroGas sseries Dry Disconnect Coupling ensures a leak-tight, automatic shut-off during connection and disconnection, significantly enhancing operational safety.
- Product Introduction
The CryoDry Series Cryogenic Dry Disconnect Coupling is a premier solution designed for the safe, spill-free transfer of cryogenic media including LNG, liquid nitrogen, and liquid oxygen. Featuring an advanced dual-poppet design, the internal valves remain securely closed until the coupling halves are fully locked, and seal automatically upon disconnection. Benchmarked against the world-class TODO-MATIC® core standards, this series eliminates fugitive emissions, protects operators from cryogenic burns, and prevents environmental hazards.

Working Principle: Single-Action "Push & Turn" Connection
Effortless Coupling: Operators simply align the Female hose unit with the Male tank adapter, push forward, and rotate clockwise. No complex levers required.
Safety Interlock: The initial rotation mechanically locks the coupling halves together while internal valves remain securely closed. Further rotation opens both valves for full, unobstructed flow.
Zero-Spill Disconnection: Turning counter-clockwise seals both internal valves prior to physical separation, ensuring virtually zero spillage or fuel splash at the split second.
Core Technical Advantages
Aerospace-Grade Aluminum (Code AL): Crafted entirely from premium aluminum alloy to ensure maximum weight reduction, heavily reducing physical fatigue for ground operators during manual handling.
High Flow & Minimal Pressure Drop: The inner geometric fluid path minimizes turbulence, ensuring fast and smooth fuel transfer rates.
Selectivity Option (Cross-Contamination Prevention): Mechanical coding slots can be customized to physically prevent incorrect connections between different fuel lines, removing human error.
Frequently Asked Questions (FAQ)
Q: Are AeroDry series couplings interchangeable with original TODO-MATIC® brands?
A: Yes. Our couplings adhere strictly to global dry-break interface specifications. The coupling dimensions and locking mechanisms match international leading brands for 100% seamless cross-connection.
Q: Can this coupling be used for aircraft underwing pressure refueling?
A: No. This product is strictly for ground bulk fuel transfer and rail/tank truck loading. It is not designed for aircraft underwing refueling. Please contact our support team for specialized underwing refueling couplers.
Q: What are the benefits of the Aluminum body and FKM/NBR gaskets?
A: The aluminum body reduces physical strain for operators due to its lightweight features. The FKM/NBR elastomers provide premium defense and sealing stability against aviation kerosene, diesel, and gasoline.
