Replacement Float set for top tap kegs this model is with the new float plug with the thinner washer to fit onto the new style taps not the original drum tap. Great float with rotating float so it will always be the right way up To fit to an original drum tap you will need to order the "float connector to fit drum tap" as well. Why not look at our Deluxe sparkler tap with built in fitting for a float so no float plug is required.
