Aluminum Threaded Flange Coupling

 2.5" aluminum flange shown

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. 

Options available:

  • Brass 
  • Storz
  • Cam & Groove couplings 
  • Custom Threads 
  • NFPA powder coated colors available
