Flytech supplies polyurethane pneumatic tubing for compressed air and vacuum lines. PU is the most flexible of the common pneumatic tubes, holding a tighter bend radius than nylon or polyethylene without kinking and shutting off flow, which is what makes it the standard choice on moving machinery, robot arms, festoon systems and anywhere the tube flexes repeatedly in service.
It also resists abrasion well, so it survives dragging across machine frames and through cable chains where a stiffer tube would wear through. Colour options let you code circuits by function, which cuts fault finding time on machines running many parallel air lines.
Key Features
• The most flexible common pneumatic tube, with a tight bend radius and high kink resistance
• Stands up to repeated flexing on robotic, moving and festoon applications
• Good abrasion resistance for runs through cable chains and across machine frames
• Available in a range of colours for circuit identification
• Cuts cleanly for push in fittings and takes standard pneumatic connectors
Specifications
• Material: polyurethane, ether based for hydrolysis resistance where required
• Typical working pressure: around 10 bar at 20°C, falling as temperature rises
• Typical temperature range: approximately -20°C to +60°C
• Outside diameter: common pneumatic sizes from 4mm to 16mm
• Supplied in coils, cut to length on request
Applications
Compressed air and vacuum lines on automated machinery, robotic cells, packaging lines, festoon and cable chain installations, and pneumatic control circuits at manufacturing and assembly plants across the Klang Valley, Penang, Johor and Malaysia wide.

Frequently Asked Questions
When should I choose PU over nylon or polyethylene tubing?
Choose PU where the tube moves, flexes or needs a tight bend radius, such as robot arms and cable chains. Nylon handles higher pressure and temperature but is stiffer. Polyethylene is the economical option for fixed runs.
What is the difference between ether and ester based polyurethane?
Ether based PU resists hydrolysis, meaning it holds up better in humid and wet conditions, which suits the Malaysian climate. Ester based PU has better oil and abrasion resistance. Specify the conditions and the right grade will be supplied.
Does working pressure change with temperature?
Yes. The published working pressure applies at around 20°C and falls as temperature rises. Derate the figure for hot environments, and confirm the derating factor for your operating temperature when ordering.
