Product Details

This gasket kit is made from a material that holds up well to brake fluid, ensuring a solid seal for your master cylinder cover. It's designed to replace the Harley-Davidson part number 45012-72, making it a straightforward swap for many Big Twin and XL models from 1972 through 1981. If you're working on a bike from that era, like a Super Glide, Low Rider, or Electra Glide Sport, this kit will help you get the job done right.

You get ten gaskets in this package, so you'll have plenty on hand for multiple bikes or future service. A good seal here is important to keep brake fluid from leaking out and contaminants from getting in, which can affect braking performance. This kit offers a well-built replacement that fits right where the original goes, simplifying your repair or restoration.
