CNC Custom Precision Turning Milling Aluminum Weld Bung for Fuel Tank

CNC Custom Precision Turning Milling Aluminum Weld Bung for Fuel Tank. Precision-machined from top-grade, solid 6061-T6 billet aluminum to ensure exceptional weldability, zero porosity, and excellent thermal stability. Manufactured via advanced CNC turning and milling to guarantee tight tolerances, ultra-smooth surfaces, and perfect 37-degree flare seating. Every item undergoes rigorous thread gauge testing to ensure perfect AN/NPT specification alignment, eliminating thread binding or loose fitting issues. Fully support customized manufacturing based strictly on your drawings or physical samples to match any non-standard thread pitch or custom step geometry. We provide a comprehensive, all-in-one manufacturing process from raw material sourcing, precision CNC processing, to post-machining surface treatments. Engineered with an appropriate shoulder height and thick weldable base to prevent thermal distortion and cracking during the TIG welding process. Capable of handling extreme pressure and fluid dynamics, making it ideal for automotive fuel cells, oil catch cans, radiators, and aerospace plumbing. As a direct factory, we offer highly competitive tier pricing, low MOQs for custom builds, and reliable lead times for volume industrial supply.
