Vanjen Weld Fittings for 3in OD Tubing

The Vanjen Weld Fittings for 3in OD Tubing from VIBRANT PERFORMANCE are precision engineered clamp ferrule assemblies designed for high-performance exhaust, intercooler, and custom tubing applications. These fittings serve as the critical connection point between aluminum tubing sections, providing a leak-free seal under demanding engine bay conditions. Whether you're building a race-spec exhaust system, upgrading an intercooler kit, or fabricating custom intake piping, this pair of aluminum ferrules delivers the reliability required for sustained performance driving.

These Vanjen clamp ferrules are machined from aluminum to accommodate 3-inch outer diameter tubing with precision tolerances that ensure repeatable, vibration-resistant connections. Each ferrule in the pair includes an integrated O-ring that creates an additional sealing layer, preventing coolant or exhaust gas leakage under pressure and thermal cycling. The natural aluminum finish resists corrosion while remaining lightweight—critical for performance applications where every fraction counts. The compact design (7.3 x 1.4 x 8.05 inches, weighing just 0.25 lbs total) makes installation straightforward in tight engine compartments without sacrificing structural integrity or clamp load capacity.

Professional fabricators and enthusiasts building custom cooling or exhaust systems benefit most from this pair, as OEM tubing transitions often require upgraded clamp hardware to handle modified boost levels or sustained high-temperature operation. The O-ring inclusion eliminates the need for separate gasket materials, streamlining assembly while improving seal longevity. Compatible with any 3-inch OD aluminum or steel tubing system—intercoolers, charge pipes, exhaust runners, and coolant hard lines—these fittings are industry-standard in modern turbo and supercharged applications where factory clips fall short.
