Order by part number, not by size
Almost everything on this page is a single small seal, and Harley-Davidson identifies them by part number rather than by dimension. Several listings share the plain title "O-RING" and differ only in the number. If you have the number from a workshop manual or a parts diagram, our Parts Finder will take it directly.
Where they go
The range covers seals from most of the bike. Engine and primary: pushrod cover O-rings 11132A and 11145A, the clutch cover seal 25416-70A, inspection cover screw seals, tappet guide and drain plug seals such as 11105 and 11900045. Fuel system: the fuel filter and O-ring 61011-04A, injector seals, fuel rail seals and the tank check valve O-ring 11323A. Also listed are coolant manifold, water pump, transmission, neutral switch and cable seals.
Buy the seal with the job
If a cover or a fitting is coming off, it is worth ordering its seal at the same time rather than reusing the old one.
Fitment
A small number are tagged for Touring, Dyna, Softail and Sportster models; most are common across the range. Confirm against your model and year before ordering, or ask our parts team.
If you know the number already, the whole Harley-Davidson parts catalogue is searchable the same way.
