The disconnect coupling includes a fitting flange to be mounted to the drain of the tank, a plug movably secured in the flange and having flow and non-flow positions, and a coupling which lockingly engages with the flange and cooperates with the plug. The coupling includes a plug drive pin and a valve disposed coaxially therein. Individual drive knobs are provided for the plug drive pin and valve to cause axial translation thereof relative to the coupling and to each other. The safety cap includes a fitting flange to be mounted to the drain of the tank, a plug movably secured in the flange, and a coupling which lockingly engages with the flange and cooperates with the plug. The safety cap ensures the proper, secure, and tight positioning of the plug in the fitting flange and maintains it in the non-flow position. 38
