Product Description
This 3.5" Marmon Bead Adapter pipe forms the female side of a Marmon Flange exhaust joint, built for trucks and equipment that need a connection you can service easily down the road. It's made from either 304 stainless steel, for the best resistance to corrosion and extreme underbody heat, or aluminized tubing if you're after a more economical build.
The bead is precision-formed to fit its matching 3.5" Flare Adapter. Once the two are clamped together with a standard V-band clamp, you have a sealed, leak-free joint that still comes apart in minutes for future service or component swaps.
- Diameter: 3.5"
- Length: 3"
- Material: Stainless steel or aluminized tubing
- OEM / MPN: 41966-L
- Pairs with: 3.5" Flare Adapter
This size shows up often on medium-duty trucks and vocational chassis, and works just as well as a Marmon-style disconnect in a custom stack or muffler delete build.
