Adaptor, carb. to Filter

Adaptor ring that joins the carburetor to the air filter housing, later renumbered 71-2086.

PN · 70-4576
Superseded by 71-2086.

This is the adaptor ring that connects the carburetor to the air filter housing, shown in the parts book under BATTERY, TOOLKIT AND AIR FILTER. It's the piece that lets the filter seat properly on the carb mouth instead of hanging loose or leaking unfiltered air past the joint.

Catalog records show this part number appearing across a handful of listings from 1967 to 1970, and it also shows up under the older E4576 form if you're working from an early parts book. Triumph later moved this part to a new number, 71-2086, so if you're chasing this down from a more recent catalog or parts diagram that's the number you may find it under instead.

If you're not sure whether this is the ring your carb and filter setup needs, give us a call with what carb you're running and we can sort out fitment before you order.
