Specifications

The AFA Industries 1S6595 Turbo Oil Supply Gasket is designed as a direct aftermarket equivalent to Caterpillar part 1S‑6595 (also cross-referenced as 7H3270) and compatible with Interstate‑McBee M‑1S6595. It seals the connection between oil feed line and turbocharger housing on Cat engines such as the 3406/3406B, C10, C12, and C13, maintaining pressure integrity and preventing leaks during high-temperature operation. Precision-cut to Cat OEM dimensions (~66 mm × 28 mm flange) with approximately 0.1 mm thickness, it weighs about 0.01 lb and ships in compact packaging (~1.1 × 2.6 × 0.1 in). The gasket is built for durability in harsh turbo environments and supports long-term reliability in heavy-duty truck and equipment rebuild applications.
