Product Description
This 4" Marmon Bead Adapter pipe is the female half of a Marmon Flange connection, sized for the higher exhaust flow of Class 8 trucks and larger diesel equipment, and built to service easily when the time comes. It's available in 304 stainless steel for long-term corrosion resistance, or aluminized tubing for a more budget-friendly rebuild.
The bead is precision-formed to seat against its matching 4" Flare Adapter. Clamp the two together with a V-band clamp and you've got a tight, leak-free joint that comes apart quickly for future service or DPF work.
- Diameter: 4"
- Length: 3"
- Material: Stainless steel or aluminized tubing
- OEM / MPN: 41967-L
- Pairs with: 4" Flare Adapter
A common size for semi-truck exhaust systems, this adapter works equally well as a direct OEM replacement or as the disconnect point in a custom stack or after-treatment rebuild.
