Aluminum Female Thread Vapor Recovery Couplings – Bottom-Side Tanker Vapor Recovery System
The HBVR-FT and HBVR-FTD series female thread vapor recovery couplings are essential components designed for the bottom-side vapor recovery system of fuel tank trucks. When connected to a vapor recovery adaptor, these couplings automatically trigger the pneumatic interlock switch on the adaptor, activating all valves in the vapor recovery system and enabling vapor flow back to the depot pipeline. Constructed with a high-quality aluminum body and probe, these couplings offer a lightweight design, smooth vapor flow, and minimal pressure drop. Handles are made of brass, and pins and rings are stainless steel, while Buna-N gaskets provide reliable sealing and long-lasting performance. The HBVR-FTD series incorporates a valve disc, effectively controlling vapor flow and preventing backflow or leakage.
Global Names and Industry Recognition
These female thread vapor recovery couplings are referred to differently across the globe:
Germany: Tankwagen-Dampfanschluss mit Innengewinde
France: Raccord de récupération de vapeur à filetage femelle
Italy: Accoppiatore di recupero vapor a filettatura interna
España: Acoplamiento de recuperación de vapor con rosca hembra
Netherlands: Dampterugwinningkoppeling met vrouwelijke schroefdraad
Nordic countries (Norway/Sweden): Tankluke dampkontrollkoppling med innvendig gjenge
UK / English-speaking markets: Female Thread Vapor Recovery Coupling for Tank Manhole
Asia and South America: commonly called Female Thread Vapor Recovery Coupling, Bottom-Side Safety Vapor Coupling, or Tanker Internal Thread Recovery Coupling
Despite the different names, the core function remains the same: efficient vapor recovery, pressure balance, and safe transport.
