SBP Premium Billet Aluminum Cap with Weld on Bung Coolant Fuel Oil Tank NON-vented

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 anodized finish. Unlike lower-quality alternatives, our weld flanges are free from coatings, ensuring a clean and reliable weld every time.
