Tappets Guide O-Rings

3 products

Tappets Guide O-Rings for Harley-Davidson seal the tappet guides in your engine's valve train, preventing oil leaks and maintaining correct hydraulic pressure. Available from Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, these O-rings cover Sportster models from the Ironhead era through to four-speed Evo units. James Gaskets and Cometic provide precision-moulded replacements in heat-resistant elastomers that withstand the high temperatures and oil exposure found inside the lower end. Replacing worn tappet guide O-rings is an essential step during any top-end or cam service, and getting the right seal first time saves you from repeat teardowns. Browse the full range below.
