Norton Connector

Exhaust balance tube connector for Norton motorcycles, cataloged for the 1975 model year.

PN · 06-3991

This is a Norton part, not Triumph — the catalog record lists it as a connector used in the exhaust system, tied to figures covering exhausts, mufflers, and passenger footpegs. Given the description and the catalog titling around it, this piece functions as a connector for the exhaust balance tube arrangement, joining sections of pipe or securing the balance tube on the system.

Our record only shows this part appearing once, tied to the 1975 model year in the catalog data. It's a small hardware item rather than a major assembly, and the entry we have is brief.

If you're trying to match this up against what's on your bike, give us a call and we'll confirm fitment before you order — the catalog note doesn't go into more detail than what's here.
