About this part

Product Details

Vibrant Performance is a well-known name in the fabrication world, and they make solid parts for custom builds. This particular weld fitting is made from 304 stainless steel, which is a good choice for charge piping because it holds up well to the demands of turbo systems. It’s designed to work with 3.5-inch outside diameter tubing, giving you a secure point to weld onto your piping.

What makes this fitting a smart choice is the included O-ring seal. When you use this with a compatible HD clamp ferrule, it creates a tight seal, which is crucial for preventing boost leaks in your charge piping. The fact that it’s made from 304 stainless steel means it’s built to last and resist corrosion, even in harsh engine bay conditions. This fitting is sold as a 2-pack, so you get two of them to get your project moving.
