Specifications

The IPD 3678756 O‑Ring Seal is precision-engineered to meet OEM standards for Cummins ISX and ISX15 15 L engines, including EPA13 and later models (single and dual cam). Made from high-temperature HNBR compound, this seal offers exceptional resistance to fuel, oil, and extreme heat cycles (as noted by PAI spec of 1.725″ ID and 0.21″ cross-section). It ensures a reliable, leak-proof seal on critical interfaces like the fuel pump or oil pump pickup tube. Supplied under IPD’s rigorous ISO certifications with a 2-year on-highway warranty , it's also included in IPD in‑frame rebuild kits. Wofford Truck Parts stocks it with fast shipping and technical support to minimize downtime during engine maintenance.
