Polyurethane (PU) tubing — also called TPU tubing (Thermoplastic Polyurethane tubing) — is a flexible plastic hose widely used in:
• pneumatic air lines
• automation systems
• robotics
• compressors
• fluid transfer
• medical equipment
• packaging machinery
It is popular because it offers:
• high flexibility
• abrasion resistance
• kink resistance
• lightweight construction
• good pressure handling
• excellent durability
Typical practical use of the colors:
Black: General-purpose air-line industrial machines, hides dirt/oil
Blue: Standard compressed air-line (very common in pneumatics)
Clear: Visual inspection of air, moisture, or fluid flow
Orange: Dedicated circuit/secondary air-line warning visibility
Yellow: Safety line, signal line, or easy identification
Clear-Blue: Semi-transparent line for visibility plus color coding
