Our J0550 self sealing Vapor Coupler is specifically designed to allow high transfer rates of vapor to flow freely from the tank truck back to the loading rack.
The J0550 has the lowest pressure drop in its class. It will allow higher flow rates at reduced pressure drop when incorporated into a well engineered vapor return system, preferably as an integral part of a vapor unloading arm.
The J0550 has a spring-closed poppet. Coupling to a tank truck vapor adapter with a poppet will open both coupler and adapter. Remove the coupler and both will close.
Ideal for use in a well engineered vapor system where multi-compartment bottom loading is taking place.
