Vibrant 2891 Polished 6061 Aluminum 90-Degree Mandrel Bend 3.5 in. OD Universal

Vehicle Fitment

• Universal - No vehicle-specific fitment. Compatible with any custom intercooler piping, air intake, or charge air plumbing application requiring a 90-degree mandrel bend in 3.5 in. O.D. aluminum tubing.

Fitment Notes

• Tube O.D. is 3.50 in. Confirm that your tubing O.D. matches before ordering.
• Centerline radius (CLR): 4.50 in. Leg length: 2.50 in. on each side.
• Mirror-polished finish - suitable for show-quality engine bay builds. Can be clear-coated to maintain finish.
• Compatible with Vibrant silicone couplers and T-bolt clamps in 3.5 in. I.D. sizing.
• Available in a full range of O.D. sizes and bend angles across Vibrant's polished aluminum tubing program.

Features

• T6061 aluminum construction - lightweight, strong, and weldable for custom fabrication
• Mirror-polished finish delivers a premium show-quality appearance in intercooler and intake builds

Product Description

The Vibrant 2891 is a mirror-polished T6061 aluminum 90-degree mandrel bend in 3.5 in. outside diameter for custom intercooler piping, air intake fabrication, and large-bore charge air plumbing. The mandrel-bent construction maintains consistent tube diameter through the full 90-degree arc - preventing the wall thinning and flow restriction that occur with conventional press-bent tubing. The 4.50 in. centerline radius produces a smooth arc suited for intercooler routing in modern engine bays where 3.5 in. charge piping is common on high-output forced induction builds.

The mirror-polished finish delivers a premium show-quality appearance well suited for visible intercooler and intake builds. T6061 aluminum accepts standard MIG or TIG welding with 4043 or 5356 filler wire and requires minimal surface preparation for fabrication. The 2.50 in. leg lengths provide straight sections for clean butt-welds on each end. Part of Vibrant's comprehensive polished aluminum tubing program available across a wide range of tube O.D. sizes and bend angles. Sold individually.
