This is a 4-inch mild steel 90-degree long-radius (L/R) elbow, used to change the direction of piping in truck exhaust systems, fluid lines, or general fabrication.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
The long-radius design reduces backpressure and flow restriction compared to a tight, short-radius bend. It is typically welded or clamped into place when building or repairing pipe runs. Because no specific manufacturer or vehicle application could be confirmed, this part is treated as a universal fitting suitable for any 4-inch steel pipe system.
