question about lily pipes

[martinshaver]

Hey everyone. I was on this forum a while ago and was gone due to some health reasons.

I have a question about some ADA style glass lily pipes. The tubing for my xp3 is 5/8" or 16mm. The lily pipe is 17mm. So would the 1mm difference in sizing be a nice tight fit or too tight? Do you use hose clamps at all?

should work fine, you can heat up the hosing in boiling water to slip it over easier. As a precaution, I use clamps for everything..
