Designed for superior durability and performance, this CNC Billet Aluminum Weld-On Flange with Cap is the exact component we trust in our fuel tanks, expansion tanks, and other non-vented applications. After struggling to source high-quality parts, we partnered directly with a CNC machining company to create our own precision-machined neck and cap.
Crafted from solid 6061 billet aluminum, this flange and cap set offers exceptional strength, corrosion resistance, and a professional raw aluminum finish. Unlike lower-quality alternatives, our weld flanges are free from coatings, ensuring a clean and reliable weld every time.
Key Features:
- Premium 6061 Billet Aluminum – Strong, lightweight, and corrosion-resistant.
- Precision CNC Machining – Ensures a perfect fit and high-quality finish.
- Raw Aluminum Finish – No coatings, making welding easy and reliable.
- Ideal for Non-Vented Applications – Designed for fuel tanks, expansion tanks, and more.
