If you contact Just Nebulizers, they are very helpful in determining what will work for you. Most tubing (which is a standard size) works with most nebulizers and compressors. The ends may be slightly different, but in 40 years with compressors and a huge variety of nebulizer cups, I have never encountered tubing that wouldn't work.

I usually have purchased my tubing in combination with the nebulizers, and changed them out together every 2-3 months. After many rounds of sterilizing, the plastic neb cups themselves can begin to tiny little cracks and crevices, so throw them out.
