Starting at $1.95, AutoBuffy stocks 2 EGR tube gaskets from SKP. This small gasket seals the metal tube that routes exhaust gases back into the intake manifold for emissions control. When it fails, exhaust leaks at the joint, triggering rough idle, check-engine lights, and failed emissions tests.
EGR tube gaskets differ by material, construction, and whether they are sold as a single gasket or as part of a kit covering both ends of the tube. Matching the material to your engine's heat and pressure output is the most important decision. Multi-layer steel (MLS) gaskets suit high-heat applications, while graphite and composite gaskets work well on moderate-duty engines.
| Option | Best for | What you get |
|---|---|---|
| Graphite composite gasket | Older or moderate-duty engines with lower EGR tube temperatures | Good conformability to slightly uneven flanges, easy crush seal, cost-effective replacement |
| Multi-layer steel (MLS) gasket | High-output or turbocharged engines with elevated EGR heat and pressure | Superior heat and pressure resistance, long service life, precise fitment to machined flanges |
| Rubber-coated steel gasket | Daily drivers needing a balance of sealing reliability and affordability | Steel core prevents blowout, rubber coating fills minor surface imperfections, moderate heat rating |
| Full EGR tube gasket kit (both ends) | High-mileage vehicles or any repair where the tube is removed completely | Gaskets for both the intake-manifold and exhaust-manifold ends, eliminates partial-repair leaks |
Begin by allowing the engine to cool completely, then disconnect any sensors or brackets obstructing access to the EGR tube before loosening the flange bolts at both ends. Clean the mating surfaces thoroughly to remove all old gasket material and carbon buildup, as a clean flat surface is critical for a leak-free seal. Install the new gasket dry or with a thin film of high-temp gasket sealant if specified, then snug fasteners evenly in a cross pattern and run the engine to check for leaks before clearing any stored codes.
