Review on High-Quality American Standard Tank to Bowl Coupling Kit - Model 7301021-0070A by Jonathan Yang

Our US Standard 6Lpf/1.6gpf Champion 4 toilet has started to leak through one of the tank screw seals. Couldn't find any replacement parts locally, none of the 'universal' kits had bolt seals. This is the ideal toilet replacement kit and requires kit #241 - part number 738756-0070. The seal I received was green. Don't worry if it's a little different in size from the old one, stretched and flattened, it will fit perfectly. The nut wrench is excellent. Much better than the plastic ones. See photo for comparison of old and new parts. By the way, anyone who needs silicone is doing something wrong.
