Stout tap/Restrictor Disc

[Covey]

John, I have a coors tap and a guinness tap the nozzels are different threads.
I found the discs very difficult to fine, thought they may appear on ebay for a euro or so. Not so... I acquired 2 over the past 6 months via pubs when they were bein serviced by guinness. thats the best approach.
Guinness rep ( if anyone knows one) may be a good person to know re servicing lines and acquiring supplies ( legally of course), with that in mind Im sure those discs are ten a penny!

Hi Bren,
What beer line are you using?
Thanks
