PU TRIUMPH OIL JUNCTION BLOCK
Oil junction block for pre-unit Triumph twins, where the oil feed lines join before routing through the engine.
This is the oil junction block for pre-unit Triumph twins, the fitting where the oil feed lines come together before splitting off to their destinations in the engine. It's a small casting that acts as a distribution point in the oiling system, so if it's cracked, stripped out, or leaking at the union nuts it's worth replacing rather than trying to nurse along.

The catalog also lists this part under the older E3355 number, which is the legacy prefix form some pre-unit parts books used before the 70-series numbering took over. If you're working from an older book and see E3355 called out, that's this same block.
We don't have a lot of extra detail on file beyond what the parts books show, so give us a call or check your own parts book for the exact figure if you want to double check before ordering.
