Description
The Fol-Da-Tank OFLC Outer Flange Kit Set is a heavy-duty flange system engineered for use with self-supporting tanks (SSTs) and Quick-Assemble series tanks. Constructed from high-grade aluminum-magnesium alloy (al-mag), the flanges are designed for strength, precision threading, and long service life in demanding firefighting applications.
When tanks are no longer in use, the outer flange kit enables fast and efficient drainage through a side-mounted flange coupling. All self-supporting tanks come equipped with reinforced heat-sealed patches around the flange to provide maximum leak protection and structural integrity.
Additionally, the OFLC flange kit can be installed on Fol-Da-Tank framed tanks, making it possible to draft directly from the tank wall using a Low-Flow Strainer. With sizes ranging from 4”–6” and available NST male or female threads, the OFLC provides a versatile and reliable solution for water transfer operations.
