Threaded Flanges – Aluminum

Threaded Flanges – Aluminum Details

Flanges are provided on all self-supporting tanks and all Quick-Assemble series tanks.  When no longer in use, the SST may be quickly drained through a flange coupling on the side.  All self-supporting tanks have reinforced heat sealed patches around the aluminum flange.   The flanges are made from high quality al-mag alloy which provides top quality castings and threads.  The flanges can also be mounted on the side walls of the FOL-DA-TANK framed tank.  This application is used when drafting with a Low-Flow Strainer attached to the side wall.

Flanges range from 1.5″ – 6″ with standard NST male or female threads available.
