Stainless Tubing

Turning a 1.5-inch tube completely back on itself in a tight space is a job for a factory bend, not a pie-cut stack or a homemade crush bend. Vibrant's 2620 is a mandrel-formed 180-degree U-bend in 1.5-inch outside diameter T304 stainless, made with a tight 1.5-inch centerline radius. That one-to-one radius lets a tube reverse direction in about three inches of space, which is what header builders and turbo fabricators need when routing primaries or wastegate dump tubes around frame rails and steering shafts.

Fabrication Notes

Because it is a U-bend, most builders cut it into the exact angles they need rather than using it whole. Mark your cuts with a wrap of tape, cut square with a band saw or abrasive wheel, and deburr the inside and outside edges. Back purge with argon when TIG welding T304 so the inside of the joint stays clean, and tack the full run in place to check clearance before final welding.

Frequently Asked Questions

Is this straight tubing?

No. Despite the product name, part 2620 is a 180-degree U-bend with 4-inch legs, not a straight length.

Which header flanges match it?

The 1.5-inch OD matches header flanges and collectors sized for 1.5-inch primaries. Check the flange port size before ordering.

Is it mandrel bent?

Yes, it is a mandrel bend, so the full diameter is held through the turn.

Fitment: Universal. Confirm the sizes and thread types listed above against your application before ordering.
