HBVR Series Vapor Recovery Couplings – Efficient, Safe, and Reliable Connections for Fuel Tank Trucks
The HBVR series vapor recovery couplings are engineered to optimize the connection between vapor recovery adaptors and oil depot pipelines, ensuring efficient vapor recovery during fuel loading and unloading operations. Designed for both hose tail and male Camlock connections, these couplings are essential for modern tanker vapor management systems, activating pneumatic interlocks and opening all associated valves automatically for smooth vapor circulation.
By securely linking the vapor recovery adaptor to the depot pipeline, the HBVR couplings enable controlled vapor transfer, minimize emissions, and prevent overpressure or accidental release, providing a safe and environmentally compliant solution for petroleum transport operations.
Global Names and Industry Recognition
|Around the world, vapor recovery couplings are recognized by different names, reflecting local industry terminology:
Germany: Tankwagen-Dampfkupplung
France: Raccord de récupération de vapor
Italy: Accoppiatore di recupero vapor
España: Acoplamiento de recuperación de vapor
Netherlands: Dampterugwinningkoppeling
UK / English Market: Vapor Recovery Coupling for Tank Manhole
Asia & South America: Commonly called “油气回收软管接头”, “油气回收快速接头”, or “安全油气排放接头”
Despite the regional variations, the core function remains the same: ensuring safe vapor recovery, activating pneumatic interlocks, and maintaining pressure balance in fuel tanks.
Key Features
High-Quality Materials: Aluminum body and middle probe for lightweight, durable performance. Brass handles for easy operation, stainless steel pins and rings for long-term reliability.
Secure Sealing: Buna-N gaskets ensure tight connections to prevent vapor leakage.
Pneumatic Interlock Activation: Connecting the coupling automatically triggers the vapor recovery adaptor’s interlock system, opening all necessary valves.
Versatile Connection Options:
HBVR-HT Series: Female threaded connection with hose tail (sizes 2”–4”).
HBVR-HE Series: Female threaded connection with male Camlock (sizes 2”–4”).
Working Pressure: 0.6 MPa, suitable for high-flow tank loading conditions.
Efficient Vapor Flow: Designed to minimize pressure drop, allowing multi-compartment loading with safe vapor return.

 | HBVR-HT Series of Vapor Recovery Couplings are usually connected to Vapor Recovery Adaptors. By connecting this coupling to the vapor recovery adaptor, the pneumatic interlock switch on the vapor recovery adaptor will be automatically activated, causing all valves of the vapor recovery system to open. It connects to the pipeline of the oil depot, enabling vapor recovery. |
