About This Product
S&S cylinder base O-ring. It is .103-inch Viton rubber. It fits 1999 to 2017 Twin Cam models with a 4-inch S&S SSW engine. It also fits stock 110-inch models with a 4-inch bore. Viton resists heat and chemicals better than standard rubber. Fit this at the base of the jug during a top-end rebuild or big bore installation to seal the cylinder.
Manufacturer part number: 50-8049.
