I sure would like to hear about those too especially if there are any airline sized ones . I’m currently cleaning out the salt buildup in my BBS hatchers with wire ties .
I found what looks to be a decent one on Chewy. I didn't trust the $1.99 ones from Amazon. @Back in the fold you need a straw sized one for airline tubing.
there is a fire arms bore brush, that gets pulled through the barrel, by a string, and a brass weight that falls through the bore…. I’m betting you could brush nearly any length of hose with a similar apparatus
