Oil feed junction gasket — pre-unit
Gasket for the oil feed junction on pre-unit Triumph twins, sealing the oil line connection near the tank.
This is the gasket that seals the oil feed junction on pre-unit Triumph twins, part number 70-1529. It shows up in the OIL TANKS section of the parts books, so its job is sealing the joint where the oil lines come together on the way to or from the tank, keeping that connection from weeping oil under pressure.

You'll also see this one listed under E1529 or GAS98, older forms of the same part number from the same catalog era. It's a small piece and an easy one to overlook when you're going through an oil system rebuild, but a tired gasket at a junction like this is a common source of a slow leak that's hard to trace.
Our records show this part appearing across catalog listings from 1960 to 1962. Given how specific pre-unit oil tank hardware can be from year to year, it's worth checking your own parts book or giving us a call before you order to make sure this is the exact junction gasket your setup uses.
