Radium Engineering Fuel Cell Weld Flange 24-Bolt Aluminum | Universal (20-0278)

Custom tanks earn their keep at the flange, where Radium's whole lid ecosystem bolts on.

The Radium Engineering Fuel Cell Weld Flange, 24-Bolt Aluminum brings the standard 6x10 24-bolt fuel cell opening to any aluminum tank you can weld: the flange TIG-welds into the tank wall and presents the bolt pattern that Radium's FCST and FCST-X surge tanks, carbon fiber lids, and fill plates all mount to. One weld turns a custom tank into a member of the standard ecosystem.

What You'll Feel

• A custom or modified tank accepting the full Radium surge tank and lid catalog
• The industry-standard 6x10 24-bolt pattern instead of a proprietary dead end
• A proper welded foundation for gaskets to seal against, flat and true

Features

• Aluminum weld-in flange with the standard 6x10 24-bolt fuel cell pattern
• Accepts Radium FCST, FCST-X, carbon fiber lids, and standard 24-bolt fill plates
• TIG-weldable into aluminum fuel tanks and cells

The Details

The 24-bolt 6x10 opening is the fuel cell world's common language, and this flange teaches it to custom fabrications: saddle tank conversions, one-off aluminum cells, and modified factory tanks all gain access to sealed surge tank lids and level sender accessories the moment the flange is welded true. Weld quality is the whole job, with the flange face kept flat so the FKM gasket seals evenly across all 24 bolts, which argues for skilled TIG work and a post-weld flatness check before the expensive lid arrives. Pair with Radium's 24-bolt FKM gaskets and stainless hardware to complete the sealing stack.
