Taper piston ring, centre
Centre (second) taper-face piston ring for Triumph engines, listed in catalog records from 1969-1972.
This is a centre piston ring listed as a taper-face ring in the Triumph parts books. It shows up in the crankshaft and piston sections of the catalog, which is where piston ring sets are typically listed even though the ring itself lives up in the bore, not down on the crank. The catalog spans appearances from 1969 through 1972, so it's tied to that general run of production in our records.

A taper-faced middle ring works as a scraper ring, helping control oil film on the cylinder wall while the top ring handles the bulk of the sealing job. Beyond that, our records don't give us bore size, ring width, or gap specs for this particular listing.
If you're rebuilding a top end and need to know which bore this ring suits, give us a call with your engine number or the piston set you're running and we'll confirm before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
