TANK FITTING
ADAPTERS
APT® tank fitting adapters provide a high quality, costeffective way to mount tank sumps to a standard 4" NPT tank
opening or 6" NPT tank opening. The bright zinc-plated cast
iron construction is not only strong, but corrosion-resistant.
The TFA-400-II and TFA-600 are easy to install and their
single hole style mounting allows sumps to be rotated to
properly align pipe entries.
