Product Description

The Radium 20-0278 Fuel Cell Weld Flange is a robust, precision-machined component designed for custom fuel cell and performance fuel system installations. Its 6x10" 24-bolt pattern makes it ideal for welding into aluminum fuel cells or tanks where a secure, leak-resistant mounting surface is required. The flange is CNC-machined from 6061 aluminum and flycut to provide a true, flat sealing face that mates perfectly with the included Viton gasket, ensuring reliable sealing under fuel system pressure.

This universal weld flange is intended for motorsport and high-performance applications where custom fabrication is necessary. The tapped 1/4"-28 bolt holes allow for straightforward attachment of fuel tanks, surge tanks, or other fuel system components, while the durable aluminum construction resists corrosion and wear associated with fuel exposure. Welding should be performed by a qualified welder familiar with aluminum fuel system components to prevent distortion during installation. The Radium 20-0278 weld flange is a versatile solution for custom fuel system projects requiring precision fit and reliable sealing.
