Burlen Updated Concentric Bowl Drain Seals...

Just saw this pop up on FB news feed today....Hopefully solves the issue of leaky/undoing float bowl drains:


I've been using Dowty type seals on mine for past few yrs without issue.

After 60 years they realized their bowl drain seals didn’t seal for s**t. I’ve found religion!

This has been in the works for a while - see here for the story on how this came to be: https://www.accessnorton.com/NortonCommando/amal-bowl-drain-plugs.39437/
