Cometic Transmission O-rings And Seals

A clean, leak-free transmission starts with sealing components that hold up under heat cycles, vibration, and years of service. Cometic brings MLS precision manufacturing to transmission O-rings and seals sized and specced for Harley-Davidson powertrains, covering Dyna platforms from 1991 to 1998, FLT and FXR machines from 1980 to early 1984, and Big Twin and Flathead engines spanning 1937 to early 1980. Cometic's engineering process treats each seal as a critical component rather than a commodity consumable, with materials selected for long-term resistance to transmission fluids and the thermal demands of the Milwaukee V-twin. For restoration builds and daily-ridden vintage Harley-Davidson machines alike, correct sealing is the difference between a reliable transmission and a steady oil seep that compounds over time. At Iron City Motorcycles in Leeds, our parts team can confirm the right Cometic seal for your specific engine family and year. Browse the full Cometic Transmission O-rings And Seals range below.
