We also offer replacement parts for your EZ-CLONE® Plant Cloning Systems. The EZ-CLONE® Drain Plug Assembly is the perfect addition to any hydroponic or aeroponic system. This 5 piece assembly is comprised of a drain plug adapter, which reduces your standard 3/4″ hose thread to a 1/2″ MPT. A white guide nut treads perfectly onto the 1/2″ MPT side of the adapter, while a standard hose cap seals the 3/4″ threading. Lastly, there are two custom-cut rubber washers that insure no leaking will occur. Just remember to put one washer on the outside of your reservoir and the other inside between the reservoir and guide nut.
