Bulkhead fitting for a tank sprayer having a non-rotatable hose adapter

摘要

A bulkhead fitting for a tank sprayer includes a tank boss and an intermediate hose-receiving adapter, each having respectively a male or female longitudinally-oriented latching portion such that when the adapter is inserted into the boss, the latching portions come together to prevent relative rotation between the boss and the adapter. The female latching portion comprises a longitudinal groove in the outer surface of either the boss or the adaptor. The male latching portion comprises a longitudinal tab extending from an outer portion of either the boss or adapter and is matable with the corresponding female latching portion. In a currently preferred embodiment, two grooves are disposed 180° apart in the outer end of the boss and two tabs are disposed 180° apart on a flange of the barbed adapter. The invention is useful in preventing inadvertent unscrewing of a bulkhead fitting by torsional forces on the hose.
