GAITOR,S/ARM PIVOT
Rubber boot that seals the swinging arm pivot point on Triumph 350/500 twins, keeping dirt out of the pivot bushes.
This is the swinging arm pivot gaiter, 82-7270 in the current numbering and F7270 or I19C under the older references. It's a rubber boot that seals the pivot point where the swinging arm meets the frame, keeping road grit and water off the pivot bushes and pin so they don't wear out early.

The catalog places it in the SWINGING ARM / SWINGING FORK and SUSPENSION UNITS AND CHAINGUARD figures, and it turns up across catalog entries running 1967 to 1974. The listings tie it to the 350 and 500 twins in that span, including T90 and T100 variants named in the parts records.
These gaiters perish with age same as any rubber boot on the bike, so if yours is cracked or torn it's worth swapping before dirt gets into the pivot. Confirm fitment against your own swingarm before ordering.
