Inductor Cone Bottom Bulk Storage Tanks

When the description says full drain or boss fitting, these tanks have a NPT thread molded onto the bottom of the tank. These come in either 1-1/2” FPT or 2” MPT. Because it is molded in as part of the tank, there is nothing preventing all of the liquid from draining from the tank.


When the description says 2” FPT fitting, these tanks have a bulkhead fittings installed in the bottom. These are all 2” FPT. These tanks do not allow the tank to drain completely because when the bulkhead fitting is installed it sticks up and is not flush with the bottom. A small amount of liquid is then left on the bottom around the bulkhead.
