used it for a one man brake bleeding setup (just some tube and an old bottle) and this fit the bill perfectly. probably way too thick for what i needed but hey it was cheap and i know it will be durable as brake fluid is super corrosive. the only downside i have to say is that when the bottle was empty the tube was so heavy it was causing it to fall over but once it filled up a little bit there were no problems, however i cant really take off stars for heavy duty tube being too heavy for an empty bottle.
