Measure twice and buy extra for errors.
Clarity vs Color
Clear tubes show coolant flow. Colored tubes match aesthetics. Some PETG can be dyed. Opaque tubes hide internal issues.
Choose clarity for inspection or color for theme.
Bending Ease
PETG bends easily with heat. Acrylic requires specific tools. Hard lines reduce flexibility. Pre-bent tubes save time.
Consider your skill level and tools available.
Durability
