SEAL, POINTS/ TIMING SIDE CRANK OIL FEED - HIGH PRESSURE RATED WITH METAL BACKING - TRIUMPH TWINS AND SINGLES
High pressure rated timing side crank oil seal with metal backing, fits behind the timing cover on Triumph twins and singles.
This is the timing side crank oil seal that lives behind the timing cover, right where the points/contact breaker sits on Triumph twins and singles. It's a high pressure rated seal with a metal backing, built to hold up against the oil feed pressure at that end of the crank rather than a plain rubber lip seal.

This seal shows up across a wide span of Triumph catalog years, and the parts books tie it to the timing cover and contact breaker area on both twins and singles. When these go hard or start leaking, you'll typically see oil weeping from the timing cover around the points housing, which is the classic symptom this part addresses.
The factory number for this seal was later updated to 70-4568P, so if your parts book or an older seal you pulled off the bike shows 70-4568, that's the same physical part under its earlier designation. It's also listed under E4568 and ENSB3V in some references.
