Compressed air powered drain cleaning tool seal.

thingiverse

I have a bunch of air cleaning tools from EBay which I sell to customers occasionally. Some people have clogged drains more than once a month so I recommend that they use this type of tool when they see the drain starting to slow down before it gets a major clog. The issue is that these cheap tools came with a cheap seal which deteriorates even if it's not being used. Several new tools in my attic have dried out, cracked seals which make the whole tool useless. This replacement seal only takes a few minutes to print out of TPU, and is a major improvement over the junk seal which comes with it. I'm sure that the TPU seal will outlast the entire tool.
