Ideal for Robotics: How Flexcoil Tubing Enhances Reliability and Aesthetics on Robotic Arms
Robotic arms never sleep on modern factory floors. They twist, reach, grab, and release all day long. What keeps them moving without drama? The tubing that feeds them air. Flexcoil PU Tubing from Aisili Pneumatic has quietly become the favorite fix for a lot of engineers. It cuts headaches, lasts longer, and makes the whole setup look sharp. Let’s break down why it’s winning fans fast.
Understanding Flexcoil PU Tubing
This isn’t some cheap garden hose. Flexcoil PU Tubing starts life as top-grade thermoplastic polyurethane pellets. Those pellets get pushed through an extruder and come out as tough, springy coils. You can pick polyester-based or polyether-based versions. Both are completely non-toxic, so they’re safe even in clean-room robots.
Watch a six-axis arm dance through its routine. Flexcoil PU Tubing stretches out smooth, then snaps right back into its neat coil. No kinks. No tangles. Just clean motion every single time.
Key Features That Stand Out
Hardness runs from Shore A 85 up to 98, so you can dial in exactly how stiff or bendy you want it. The polyurethane laughs at scratches and scuffs. Picture a robot sliding past sharp metal edges all shift long. This tubing shrugs it off.
It works happily from -15°C to 60°C. That covers most shop floors, even in winter or under hot lights. Working pressure tops out at 10 bar, with a burst safety margin of 25 bar at room temperature. Translation: it won’t pop on you when the compressor hiccups.
Colors? Take your pick—black, dark blue, bright blue, crystal clear, green, red, orange, yellow. Match your company colors or make maintenance guys spot leaks in two seconds.
Materials and Build Quality
Ester-based polyurethane brings the toughness. It fights tears, bangs, and even UV rays. The coil springs back like new after every stretch. In tight robot wrists where space is measured in millimeters, Flexcoil PU Tubing slips in without forcing joints out of whack.
Standard sizes run from 3 mm to 25 mm outer diameter. Coiled lengths go up to 15 or 20 meters depending on the model. It’s light, strong, and built for the real world.
How Flexcoil PU Tubing Boosts Robotics Performance
Robots have to be rock-solid and look good doing it. Flexcoil PU Tubing checks both boxes without breaking a sweat.
Enhancing Reliability in Demanding Environments
Downtime costs real money. One burst hose can stop a whole line. Flexcoil PU Tubing fights back with serious abrasion resistance. Think about a spot-welding robot in a truck plant—sparks everywhere, metal dust flying. This tubing just keeps breathing.
It bounces back fast after stretching, perfect for arms that extend and retract a thousand times a shift. I’ve seen shops drop hose replacements from monthly to almost never after switching. Air flow stays steady. Grippers grab exactly when they should. No surprises.
Improving Aesthetics for Modern Workspaces
Nobody likes a rat’s nest of tubes. Loose hoses scream “old school.” Flexcoil PU Tubing coils tight and stays that way. Pick clear blue and you can actually see the air moving. Or go bright red so everyone knows that’s the main feed.
In cobot zones where people work shoulder-to-shoulder with robots, tidy looks build confidence. A clean robot feels safer. Clients notice too—when they walk the floor for a demo, sharp coils say you run a tight ship.
Coil inner diameters start at just 26 mm. That means the tubing hugs the arm instead of flopping around like loose spaghetti.
Real-World Applications on Robotic Arms
This stuff is already out there getting dirty and proving itself.
-
Pick-and-place lines: air hits the grippers fast and clean.
-
Welding cells: heat and slag don’t faze it.
-
Inspection bots crawling through tight frames: it bends where straight tube can’t.
-
Automated screwdrivers: no hose drag slowing the cycle time.
I watched a packaging plant shave two seconds off every cycle just by cleaning up the air lines with Flexcoil coils. That adds up to thousands of extra boxes a day.
Specifications You Can Count On
Numbers matter. Here’s a quick cheat sheet of the most popular sizes:

| 1410 | 14 | 9.5 | 3-15 | 46/58 | 25 | 10 |
| 1612 | 16 | 11 | 3-15 | 46/58 | 25 | 10 |
Need something bigger or custom? They’ve got up to 25 mm OD and special colors on request.
Benefits That Go the Extra Mile
It’s tough on impact, light on the arm motors, and plays nice with standard push-to-connect fittings. Snap it in and you’re done—no fighting stiff hose around corners. In food or pharma robots, the non-toxic material keeps inspectors happy. And because it lasts longer, you’re tossing fewer coils in the trash.
