Copper Sump Plug Seal Honda CB1100
Honda CB1100, all versions incl EX/RS from 2012 to today (model codes SC65/SC78).
High-quality copper seal for "do-it-yourself" oil changes.
It's tempting to reuse the pan gasket already there but a new seal provides a guarantee of no-leaks, without having to force the thread.
12 month warranty.
