anyone know of anyplace to get similar silicone tubing that lucky supply sells to replace the nipples on machines, i ordered some off ebay it was a bit too tight its tough to find the exact size, it needs a inside diameter of 2.5mm and an outer diameter of a little less then 5mm, 5mm stuff works but is super tight, i was just going to order thru luckys but it looks like they want to charge me 43 dollars shipping by fedex on a 10 dollar order....
