Choosing tubing
Match the material to the media and pressure, and the size to your fittings. Start with the tubing material guide, confirm dimensions with OD vs ID sizing, and check limits on the pressure rating chart. For chemical feed, the poly tubing compatibility chart tells you what holds up.
Connect it
Tubing pairs with compression, push-to-connect, and hose barb fittings depending on material and pressure. Not sure which? See choosing tube fittings. DOT air brake line has its own rules, covered in the DOT compliance guide.
