Oil control ring
An oil control ring for the crankshaft and connecting rod assembly, listed under Triumph part number 70-6865 (also known as E6865).
70-6865 is an oil control ring listed in the crankshaft and connecting rods section of the Triumph parts books, with the earlier E6865 number showing up in older catalog listings for the same piece. As the name says, this ring's job is to scrape excess oil off the cylinder wall on the piston's downstroke and route it back to the sump, keeping oil consumption in check and helping the compression rings do their work without getting fouled.

This one shows up in catalog rows spanning 1967 through 1971, so it's tied to the crankshaft and connecting rod assemblies of that era's engines rather than being a universal fit across the whole range. If you're rebuilding a top end and matching bore size, check what's actually in your piston set before ordering rings piecemeal.
Give us a call if you're not sure this is the right ring for your bore or piston setup — we can confirm before you order.
