I gave up trying to use bits of hose on the bleed nipple after finding it gets in the way and knocks the jar over when tightening the nipple. Plus, not all the fluid come out that way… a fair bit leaks around the threads.
To drain lots out to replace the fluid I’ll take the calliper off and hold it upside down over a jar.
If just getting air bubbles out and there’s not going to be much to catch, holding a rag around the nipple is sufficient.
A useful tip is to squirt some WD40 or equivalent into the nipple once it’s tightened (poke the straw down the nipple). This displaces the remaining brake fluid which would attract moisture… I’ve never had a seized nipple since I started doing that.
