James Gaskets O-rings

21 products — part of all O-rings

James Gaskets O-rings for Harley-Davidson cover the Twin Cam and Milwaukee-Eight era sealing requirements that come up repeatedly in service and rebuild work. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks James Gaskets O-ring sets for 1999–2003 Twin Cam, 2007–2026 Softail, Dyna, FLT Touring, and Trike platforms, and 2014–2025 FLT with Twin-Cooled engine applications. The material specification matters more than it appears on an O-ring: Harley-Davidson uses a range of sealing applications from pushrod tubes running motor oil to fuel injection components in contact with modern ethanol-blended fuels, and a generic NBR ring can degrade quickly in the wrong application. James Gaskets specify the correct compound for each Harley-Davidson application in their catalogue — fluorocarbon where fuel resistance is needed, NBR where oil resistance is the priority.
