VS Pneumatic is a PU Coil Manufacturer in India with high quality coiled polyurethane tubing used in pneumatic, automation and industrial industries. We are a reputable manufacturer of Polyurethane coil and are experts at producing flexible and retractable coil tubing that is durable, with routing of air supply being both convenient and free of tangles. We have a variety of different diameters that include PU Coil 4 mm, PU Coil 10 mm, PU Coil 12 mm, and accompanying PU Coil Fittings to meet the needs of all machines and workshops.
All coils are subjected to rigorous quality assays in order to have uniform recoil memory, pressure tolerance, and long-term capacity to stretch under repeated stretching. Our coils are relied upon in large industrial facilities as well as small workshops due to their strength and reliability. Bigger and improved ways of production are always being invested in, to keep our sizing, finishes, and material grades in line with the new industry requirements, which makes us a reliable manufacturing partner to businesses in India.
What Are PU Coils?
A PU Coil is a flexible polyurethane tube in the form of a spring, which is said to be stretched and retracted automatically and is used to keep the air lines organized and not tangled and dragging on the floor. As opposed to straight tubing, a PU Coil tube is able to snake back into form when it has been used, thus it is suitable in mobile tools, workstations and equipment that need to be moved frequently.
Key Characteristics:
- Self-retracting design
to remove loose, trailing air lines.
- Lightweight, but strong enough
it does not kink even when stretched repeatedly.
- Comes in various sizes
such as PU Coil 4 mm in small tools and PU Coil 12 mm in tools with more airflow requirements.
- Excellent abrasion resistance
to the workshop and factory floor.
- Large temperature operating range
to maintain performance.
- Offered as PU Coil pipe and PU Coil hose options
to connect to various requirements
Uses of PU Coils in Various Industries
Coiled polyurethane tubing is common everywhere there mobile and clean air-lines are of concern:
- Automotive Workshops
driving pneumatic powered equipment such as impact wrenches and spray guns.
- Manufacturing Units
provision of air to portable equipment and assembly stations.
- Automation & Robotics
no-tangling connection of air to moving robotic arms.
- Construction Sites
pneumatic power to portable equipment.
- Painting and Spray Booths
easy access and flexibility without congesting the work-space.
- Packaging Lines
actuators supporting mobile pneumatic actuators that are compact.
PU Coil Weight-Bearing Capacity & Load Considerations
A PU Coil is not a structural load-bearing coil, it is an air and fluid transfer coil, it is designed to transfer air and fluid, but not to support a load, again, knowing the limits of tension and stretch are crucial to safe and long-term operation, particularly when used in a continuous-use environment.
- Rated Stretch Length
Each coil has a limit of safe extension length; repeatedly stretching beyond this limit causes the material to become weaker, and it rapidly loses recoil memory.
- Tension at Fittings
The connection areas are the most stressed when stretching and retraction are involved. Installation of the correct strain-relief fittings will prevent joint pulling damage.
- Coil Diameter vs Load
Larger coils such as PU Coil 10 mm and PU Coil 12 mm can be used to operate at higher pressure loads as well as more frequent stretching cycles compared the smaller coils such as PU Coil 4 mm which are only suited to lighter loads.
- Suspended Weight Suspended weight
When the weight of a spray gun, tool or attachment is suspended on the end of a coil, a coil with a bit more thickness in its walls will minimize the amount of sag and early wear.
- Cycle Frequency Effect
Coils in high frequency, repetitive stretching systems (such as assembly lines) have greater mechanical stresses and must be rated to be operated continuously as opposed to occasional use.
- Environmental Load Factors
Temperature extremes may have an effect on the material elasticity, which in turn indirectly influences the amount of stretch and load a coil has when operating safely.
Rapid hint: When choosing a coil to use in equipment that swings or pulls on the tubing on a regular basis, always size larger and check load requirements with your supplier instead of thinking some standard rating is applicable.

Selecting PU Coils and Fittings
The selection of the appropriate coil influences the airflow, safety, and equipment functionality:
- Check pressure rating
adjust coil to the working pressure of your tool or machine.
- Select an appropriate diameter
PU Coil 4 mm is appropriate with compact tools; PU Coil 10 mm and PU Coil 12 mm are appropriate with higher air-flow applications.
- Take into account coil length
sufficient stretch length in your working area.
- Install fittings properly
pair PU Coil Fittings to make sure connections are secure and leak free.
- Grade of check material
use more grade polyurethane where there is an outside application or high temperature.
Quick tip: It is always important to verify equipment specifications with your supplier prior to ordering.

We collaborate intimately with our distribution partners to make sure that PU recoil hoses, polyurethane coil tubing, and other commonly ordered items pass through a lean, reliable logistics process – enabling hardware retailers, industrial suppliers, and automation firms to meet their orders on time without having to compromise quality. This has established distribution relationships that are enabling businesses to have confidence in planning their inventory in relation to fast and predictable restocking of PU coils and other associated tubing solutions.
Typical PU Coil Issues and PU Coil Prevention
Although a PU Coil is constructed to be durable and used repeatedly, improper handling or choice of the coil can result in premature performance problems. In this case, the following is what to look out on:
- Loss of Recoil Memory
After a certain length of time or overstretching a coil can lose its springing back shape. Do not extend the coil to lengths exceeding those specified and properly store it when not in use.
- Connection Disconnection Bending The Tube At Connection Points
Bend the tube of PU Coil too sharply around fittings could kink, closing off airflow. Proper strain-relief fittings should be used, and tight fittings should not be made at the connection.
- Reduced Airflow
This may be due to the choice of an undersized coil, e.g. a PU Coil 4 mm instead of PU Coil 10 mm or PU Coil 12 mm. Always size coil to air-flow needs of your equipment.
- Cracking or Stiffness
Polyurethane may become brittle with time due to long UV exposure, or when exposed to extreme cold. Use UV-resistant grades where the application is outdoor and cold-resistant grades where it is low temperature.
- Fittings Leaks at Fittings
Fittings leakage is normally due to incompatible, or corroded, PU Coil Fittings. Fittings must fit the size of the coil used and check them now and then to check their wear or looseness.
- Sagging or Dragging Coils
It occurs when the coil is stretched past the intended length of operation more than once. The coil length should be chosen to match the size of your workspace so that you are not using full maximum-stretch all the time.
Tip: Have your Polyurethane coil regularly checked over, to check for stiffness, discolouration or fitting wear - early detection will ensure that you do not have to suffer unforeseen idle time and also increases total service life.
