I know about K&S, but the selection is very limited. I see numerous online sources for stainless steel hypodermic type of tubing. Anyone have a good source that does small orders? I'm looking for +-1mm and/or 1/16" to maybe 5mm and/or 3/16" diameter, very thin wall, don't know what grade. It would be nice if they offered variety packs. I see some have 5' lengths, a bit long. Primary use would be exhaust tips. Wanted to ask before I rolled the dice......
