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 designed for bottom-side vapor recovery systems on fuel tank trucks. When you snap this coupling onto the vapor recovery adapter, it automatically trips the pneumatic interlock switch. That opens up the entire recovery loop, letting fuel vapors vent safely back into the depot's pipeline rather than escaping into the air. Honestly, it just makes the whole loading and unloading process a lot smoother, faster, and way more secure for your drivers.

We went with high-grade aluminum for the coupling body and the probe because no one wants heavy, clunky hardware on their rigs, but it still has plenty of structural strength to handle daily abuse. The internal design keeps vapor flow moving freely with almost zero pressure loss. For the wear points and sealing, it packs a spark-resistant brass handle, rugged stainless steel pins and rings, and fuel-resistant Buna-N gaskets—which work together beautifully so you aren't swapping out parts every few months. Now, if you opt for the HBVR-FTD model, you get a built-in valve disc. That's a massive help because it acts as a check valve, blocking unwanted backflow and stopping vapors from leaking out when you disconnect.

You'll find these couplings deployed all over the place—on fuel tank trucks, petrochemical transit rigs, and busy multi-compartment loading racks. It's a straightforward, zero-fuss design that installs easily and just does its job day in and day out. If you're trying to build a reliable vapor recovery system where safety and efficiency actually matter, the HBVR-FT series is a rock-solid choice.
