Injector O-Rings Ford 6.0L Diesel

The MAHLE ORIGINAL/CLEVITE Injector O-Rings for Ford 6.0L Diesel (MPN GS33711) is a critical fuel injector seal kit engineered to restore compression and prevent fuel leakage at the injector interface on Ford PowerStroke engines. The 6.0L diesel platform is known for injector issues that develop over time, and proper sealing is essential to maintain fuel pressure, combustion efficiency, and engine longevity. This kit includes rubber o-rings, crush washers, d-rings, and snap rings—all the seals necessary for a complete injector installation or rebuild.

The fuel injector seal kit's elastomer composition is formulated to withstand the high-pressure, high-temperature environment inside the 6.0L combustion chamber, where fuel pressures regularly exceed 25,000 psi. MAHLE ORIGINAL is the OEM supplier for Ford PowerStroke components, so this kit meets factory specifications for material hardness, chemical resistance, and compression set. The included crush washers ensure proper seating geometry when the injector is torqued into place, while the d-rings and snap rings provide additional retention and load distribution.

Technicians and powertrain rebuilders working on 6.0L diesel engines—whether managing high-mileage trucks, addressing rough idle symptoms, or performing a full injector service—rely on OEM-equivalent sealing kits to avoid repeat failures. Failed injector seals produce white smoke, rough running, and potential water contamination in the crankcase if fuel passes the rings. Using verified MAHLE ORIGINAL components ensures the repair holds under sustained boost and load.
