Vibrant Performance 12046 Aluminum Straight Tubing Coupler, 1-Inch OD, 3-Inch Long

The Vibrant Performance 12046 Aluminum Straight Tubing Coupler provides a reliable connection between compatible tubing sections in automotive and fabrication applications. Designed for tubing with a 1-inch outside diameter, this joiner coupler creates a clean, aligned transition while supporting efficient custom intake, exhaust, intercooler, and fluid-routing projects.
Constructed from lightweight aluminum, the coupler offers a practical balance of strength, corrosion resistance, and ease of handling. Its natural aluminum finish delivers a clean, functional appearance and can be left as-is or incorporated into a customized fabrication system. The straight design is well suited for joining two tubing sections along the same axis without introducing an angle or offset.
The 3-inch overall length provides ample joining surface for a secure installation when used with appropriate clamps, beads, sleeves, or other compatible fabrication hardware. For best results, verify tubing outside diameter and connection requirements before installation. The coupler is supplied individually and is identified by Vibrant Performance part number 12046.
