Expobar 3 Hole Steam Tip + O'ring - C30370195 From  £34.44

I purchased this for our Expobar Office Lever and, although that machine is not listed under "compatible models" it works perfectly. The stock tip is really not very good, and this is a fantastic upgrade if you own a Lever model.

If you own an Expobar Brewtus IV I'd say that switching over to this tip is a must (as opposed to the single hole one that comes with the machine)
