Subaru 806917080 — O-Ring
Overview
O-ring seal Subaru 806917080 seals fluid connections within engine oil circuits and cooling lines to prevent fluid loss under high pressure. Manufactured from fluorocarbon rubber (FKM), this component withstands operating temperatures ranging from -40 °C to +150 °C. The seal features a circular cross-section with an internal diameter of 17.5 mm and a thickness of 2.5 mm. OEM reference number Subaru 806917080 matches factory specifications for precise housing seat fitment. Material composition resists engine oil, synthetic lubricants, coolant additives, and fuel residues without hardening. Shore A hardness rating of 70 units prevents extrusion from the mating groove during pressure spikes.
Fitment includes Subaru Impreza, Forester, Legacy, Outback, Tribeca, and XV models produced between 1998 and 2022. The seal locates on EJ20, EJ25, EZ30, FB20, and FB25 boxer engines within the oil pump assembly, oil cooler housing, and cooling pipe junctions. Renewal is required during engine overhaul, component disassembly, or when fluid seepage appears around mating surfaces. Rubber seals undergo thermal set, hardening, and degradation over extended service intervals. Reusing a removed seal leads to joint leakage because compressed rubber fails to regain its original cross-sectional profile.
