Norton Pipe, Breather (Separator to Balance Tube)
Breather pipe running from the oil separator to the balance tube, part number 06-5499.
This is the breather pipe that runs from the oil separator to the balance tube, part number 06-5499. The catalog places it in the oil tank and fittings section, alongside the oil lines and cartridge filter, so it's part of the oiling system's breathing arrangement rather than a pressurized oil line itself.

We only see this listed once in the catalog, tied to the 1975 model year, so we don't have much more to go on beyond what's here. If you're matching this up to a bike, give us a call and we'll confirm fitment before you order.
It's a simple pipe with one job: letting the crankcase breather system vent through to the balance tube. Not much to it, but getting the right one matters for keeping that breathing circuit sealed up properly.
Sorry if we got something wrong here. If you think this information isn't correct, .
