5/8 tubing

[dph]

Hi just joined the forum after a return to kit brewing.

My primary fermenting bin as large tap on it. I have seen the suggestions on the site about stepping down from 3/4" to 5/16" for bottling direct.

However I can not locate any 3/4" tubing anywhere. Any ideas?

Many thanks.

Thanks. I seem to have confused myself between 3/4 and 5/8 (even in just the one post).
