Cummins 2007.5–2018 Ram 6.7L Cummins EGR Crossover Pipe Gasket – Concave (3949910)
Description
When servicing the EGR cooler or crossover pipe on your 6.7L Cummins, replacing the gasket is cheap insurance against exhaust leaks.
The Cummins 3949910 Concave EGR Crossover Pipe Gasket is a genuine OEM replacement designed to create a proper seal between the EGR crossover pipe and EGR cooler. Because this is a crush-style sealing gasket, it should never be reused after removal. Installing a new gasket helps ensure a proper seal and reduces the chance of exhaust leaks during reassembly.
Whether you're replacing the EGR cooler, cleaning the crossover pipe, or performing other engine service, installing a new factory gasket is always recommended.
Features
- Genuine Cummins OEM gasket
- Cummins Part Number: 3949910
- Concave crossover pipe gasket
- Factory fit and sealing performance
- Crush-style metal gasket
- Helps prevent exhaust leaks
- Direct OEM replacement
- Ideal during EGR cooler or crossover pipe service
Why Replace the Gasket?
The factory EGR crossover gasket is designed to crush when installed, creating a tight seal between the mating surfaces.
Once compressed, the gasket cannot reliably reseal if reused. Reinstalling an old gasket increases the likelihood of exhaust leaks, soot buildup, and additional labor if the system must be disassembled again.
Replacing the gasket while everything is apart is inexpensive insurance for a proper repair.
Glacier Tech Tip
Whenever the EGR crossover pipe is removed, inspect both sealing surfaces for carbon buildup, corrosion, or damage before installing the new gasket.
Clean, flat mating surfaces combined with a new OEM gasket provide the best opportunity for a long-lasting, leak-free seal. Reusing old crush gaskets is never recommended.
Why Choose Genuine Cummins Parts?
Aftermarket replacement gaskets can vary in material quality and fitment.
Genuine Cummins gaskets are manufactured to meet the original sealing specifications for your engine, helping ensure proper fit, durability, and sealing performance.
For critical exhaust sealing applications, OEM components remain the preferred choice.

Common Failure Point
One of the most common causes of exhaust leaks after EGR service is reusing the original crossover gasket. Because the gasket is designed to crush during installation, it loses its ability to seal properly once removed.
Installing a new OEM gasket helps prevent exhaust leaks, soot buildup around the flange, and unnecessary rework after the repair.
