Specifications

The AFA Industries 1090072 Seal O‑Ring is built to meet high-performance standards in Caterpillar engine systems. Featuring a 1.6 in (40.64 mm) inside diameter and a 0.21 in (5.33 mm) cross-section (SAE dash size 326), this seal resists temperatures from -40 °F to 275 °F and withstands diesel fuels, petroleum oils, lubricants, ozone, and water-based engine coolants. Constructed of HNBR rubber (Hardness 78) with PTFE coating to minimize installation damage, it provides excellent durability and helps prevent leaks in hydraulic and coolant circuits. This seal is commonly used in Caterpillar C15/3406E oil pump pick‑up assemblies and other heavy‑duty sealing applications in trucks and construction equipment built from 1998 onward.
