Vibrant 13172 Transition Adapter 4" Oval to 4" Round 6" Length

The Vibrant 13172 Transition Adapter provides a seamless conversion from 4-inch oval tubing to 4-inch O.D. round tubing over a 6-inch length. This precision-engineered adapter is essential for custom exhaust fabrication where space constraints require oval tubing in certain sections while maintaining standard round piping elsewhere.

Key Features:

• Smooth transition from 4-inch oval to 4-inch outer diameter round tubing
• 6-inch overall length provides gradual, flow-optimized transition
• Constructed from T304 stainless steel for superior corrosion and heat resistance
• Mandrel-bent construction maintains consistent wall thickness and inner diameter
• Non-magnetic stainless steel alloy with high chromium and nickel content
• Ideal for custom exhaust systems, turbo applications, and performance builds

T304 stainless steel construction ensures this transition adapter will withstand the harsh acidic, high-heat, and corrosive conditions found in exhaust systems far better than mild steel alternatives. The mandrel-bent design eliminates restrictions and turbulence, maintaining optimal exhaust flow through the shape transition.
