S&S O-rings

6 products — part of all O-rings

S&S Cycle O-rings are the seals that keep fuel and oil where they belong in an S&S-equipped Harley-Davidson engine or fuel system. Engine and carburettor rebuilds on S&S components require O-rings matched to the specific bore sizes and groove dimensions that S&S uses — substituting generic hardware-store O-rings risks mismatched dimensions, incorrect durometer for the fluid temperature involved, or material that degrades faster than the application demands. S&S produces O-rings for their carburettors, fuel systems, and engine components to the specifications those assemblies require, making sourcing straightforward when a rebuild or replacement is needed. For Harley-Davidson owners running S&S carburettors or engine components, keeping the correct O-ring sizes on hand avoids delay during a rebuild. Iron City Motorcycles in Leeds stocks S&S engine and fuel system components so that customers can source replacement seals alongside the other S&S parts needed for a service.
