It attaches to the API RP 1004 bottom loading adapter on the trailer and enables a quick, unrestricted gravity drop of fuel through a 22.5-degree downward angle. The assembly includes a heavy-duty chain and a large gasket to minimize product loss. Replacement is typically needed when the gasket wears out, the chain breaks, or the adapter develops corrosion or damage.
