Vibrant T304 SS 4 Bolt Flange for 3.5in O.D. Oval Tubing

This Vibrant Performance flange provides a precise weld-on connection for 3.5 inch outer diameter oval exhaust tubing in custom fabrication projects. It delivers a secure 4-bolt seal that withstands extreme heat and pressure in performance exhaust systems. Ideal for drag racing diesel trucks and high-horsepower street builds requiring durable oval tubing joints.

Key Features

  • T304 Stainless Steel Construction: Resists corrosion and maintains integrity under 1600+ degree exhaust temperatures for long-term reliability.
  • 3/8 Inch Thickness: Heavy-duty 0.375 inch plate adds strength to prevent warping and ensures flat mating surfaces for tight seals.
  • 4-Bolt Design: 5/16-18 bolts on 3.12 inch centers provide even clamping force to eliminate leaks at high boost levels.
  • Precise Oval Dimensions: Fits 3.5 inch OD tubing with 3 inch height and 4.12 inch width for seamless integration in mandrel-bent systems.
  • Polished Finish: Smooth surface reduces turbulence and enhances visual appeal in exposed exhaust setups.

Product Notes

  • Sold individually or in packs of 5 for bulk fabrication needs.
  • Designed for welding to oval tubing ends without distortion.
  • Compact design fits tight clearances in chassis-mounted exhausts.

Installation Notes

  • Professional installation recommended.
  • Weld-on application requires TIG welding for stainless steel compatibility.
  • Compatible with 5/16-18 x 1 inch grade 8 bolts and lock nuts not included.

Fabrication

Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...

Flanges

Flanges

Exhaust flanges are the bolted connection points where exhaust manifolds mate to downpipes, where sections of exhaust pipe join at catalytic converters and muffler inlets, and where aftermarket headers connect to factory or custom collector sections, making flange quality and correct material specification critical for maintaining leak-free exhaust connections under the extreme temperature cycling that performance exhaust systems experience. Flange warping and gasket failures at exhaust connection points are among the most common exhaust leak sources on both stock and modified vehicles, as the thermal expansion differences between the flange material and the connected pipe cause progressive face distortion over time that breaks the gasket seal. Performance exhaust builders use thick-cut mild steel, stainless steel, or titanium flanges in precise O.D. profiles matched to their pipe diameter to ensure the clamping surface remains flat through hundreds of heat cycles. This collection c...
