Product Description

The Vibrant Performance 12548 VanJen Aluminum Weld Fittings are purpose-built for custom charge piping and exhaust fabrication requiring a clean, reusable modular connection. Made from T6061 aluminum, these weld-on fittings deliver a lightweight yet strong interface that pairs directly with the Vibrant VanJen HD Clamping System for a leak-proof, professional-grade seal on 4.000 in. O.D. tubing. Each fitting includes an O-Ring for a secure pressure-tight connection right out of the box.

Sold as a pair, the Vibrant 12548 is the go-to solution for builders who want to replace traditional flanges or slip-fit connections with a more serviceable and modular system. Note that a complete connection also requires the Vibrant VanJen Clamp (#12568) and Union Sleeve (#12588), both sold separately. These fittings are universally compatible with any vehicle platform using 4 in. O.D. aluminum charge or exhaust piping.
