You’ll be glad to hear that our expertise in producing nylon tubing ensures your pneumatic systems operate with maximum reliability.
It’s good to see that these tubes can withstand working pressures up to 50 bar, providing a stable safety margin for your facility.
The journey from raw material to a finished product is a precise engineering feat. We take high-quality polyamide resin pellets and process them through a calibrated extrusion line at temperatures exceeding 220°C.
As a result of this controlled thermal cycle, the resin forms a continuous tube with a wall thickness tolerance of +/- 0.1 mm.
For your high-pressure pneumatic installations, nylon is the industry standard for a reason. It’s good to see that the material maintains dimensional stability even under vibration or rapid pressure cycles.
In our view, this makes it the most dependable choice for automated assembly lines that require millions of cycles without failure.
The Chemistry of Polyamide Tubing
Nylon belongs to a family of synthetic polymers known for their exceptional molecular chains.
These chains form a highly crystalline structure, giving the finished tube a tensile strength of approximately 60 MPa. You are in luck if your project requires a specific balance of rigidity and movement.
We offer both semi-rigid and flexible variants to suit your specific installation environment. The flexible versions incorporate 12%-15% plasticisers by weight to lower the flexural modulus.
This modification allows you to achieve a bend radius as small as 25 mm without risking the tube wall collapsing or kinking.
Why Nylon Outperforms Standard Polymers
When you compare nylon to standard PVC, the differences in durability are immediate and measurable. For instance, nylon typically offers a tensile strength that is three times higher than that of standard unreinforced PVC alternatives.
It also features a Shore D hardness rating of 60 to 80, providing a hard surface that resists deep scoring.
This abrasion resistance is vital for moving machinery parts that cycle thousands of times per day. You’ll find that our heat-stabilised grades operate safely at continuous temperatures reaching 100°C.
Additionally, our UV-stabilised options are designed to resist material degradation for over 10 years in exposed outdoor environments.

Frequently Asked Questions
What is the difference between flexible and semi-rigid nylon tubing
Flexible nylon tubing typically features a flexural modulus of 400 MPa, while semi-rigid versions reach 1200 MPa.
You'll find that the flexible grade allows a tighter 25mm bend radius for a 6mm tube, which is helpful in compact machinery. In our view, this flexibility makes it easier for you to install in tight engine bays or control cabinets.
Semi-rigid tubing provides the structural integrity needed for higher-pressure systems and resists kinking under mechanical stress.
You'll be glad to hear that both types maintain their shape up to their rated limits, providing reliable performance across diverse industrial settings.
Can nylon tubing be used for high-temperature applications?
You're in luck if your application runs at 80°C, as this is the standard continuous operating limit for our nylon tubing.
For instance, it can withstand short-term spikes of 120°C without losing its structural integrity, which earns our thumbs up for industrial reliability.
It's good to see that the material remains stable at these temperatures, though you should expect a reduction in pressure rating as the heat increases.
At 60°C, the effective working pressure typically drops to 50% of its value at room temperature.
As a result, you must calculate your system requirements based on the peak thermal exposure of your specific environment.
Is nylon tubing resistant to petrol and diesel fuel
You'll be glad to hear that nylon tubing offers exceptional resistance to both petrol and diesel fuel.
It maintains its integrity with a volume swell of less than 0.5 per cent after 500 hours of immersion, ensuring your fuel delivery systems remain leak-free.
In our view, this chemical stability makes it the safest choice for automotive and garage equipment.
The material also resists most hydraulic fluids and oils used in heavy machinery. You'll find that this durability extends your equipment's service life and reduces the need for frequent maintenance.
What are the standard sizes for pneumatic nylon tubes in the UK
Standard metric sizes in the UK focus on outside diameters, including 4mm, 6mm, 8mm, 10mm, and 12mm.
You'll also encounter imperial sizes such as 1/4 inch and 3/8 inch in many British manufacturing plants.
It's good to see these options available to ensure your legacy equipment remains fully operational without the need for expensive adaptors.
We provide these in various wall thicknesses, such as 0.75mm or 1.5mm, to suit different pressure requirements.
You'll find that having access to both metric and imperial standards significantly simplifies your procurement process.
How does moisture absorption affect the performance of Nylon 12?
Nylon 12 absorbs only 1.4 per cent moisture by weight at saturation, which is much lower than the 9 per cent seen in Nylon 6.
As a result, your tubing stays within a 0.05mm dimensional tolerance, providing you with a consistent fit for push-in fittings.
You'll be glad to hear that this low absorption rate prevents the material from becoming brittle in dry conditions.
High moisture resistance also ensures the tube's physical strength doesn't degrade when exposed to humid British weather.
In our view, this stability makes Nylon 12 the most dependable grade for outdoor pneumatic installations.
Can I get nylon tubing in custom colours for identification?
You're in luck because we can manufacture bespoke nylon tubing in specific RAL or British Standard colours to match your brand identity. For instance, we can produce exact matches for safety-critical lines, which is really nice to see when you need to distinguish between air and fluid channels.
This customisation helps you prevent cross-connection errors during complex system assemblies.
We also offer transparent options for monitoring fluid flow or detecting air bubbles in your lines. You'll find that these colour-coded solutions improve the safety and efficiency of your workspace.
What is the maximum pressure rating for a standard 10mm nylon tube
A standard 10mm nylon tube with a 1.5mm wall thickness offers you a maximum working pressure of 24 bar at an ambient temperature of 20°C.
You'll find this rating is sufficient for most factory air lines. It's good to see that the burst pressure is often three times higher at 72 bar, providing you with a three-to-one safety factor.
If your system operates at 40°C, you'll see the working pressure limit decrease to approximately 17 bar.
As a result, you should always check the temperature-pressure charts before finalising your system design.
Is Nylon 11 better than Nylon 12 for outdoor environments?
Nylon 11 is generally the superior choice for outdoor use because it retains its impact strength at- 40°C and offers higher UV stability. You'll be glad to hear that it's also a bio-based polymer derived from castor oil, meaning you get a high-performance product that supports your environmental targets.
In our view, the slightly higher cost is justified by the increased longevity in direct sunlight.
Nylon 12 is still a very capable material, but it can experience a 10 per cent faster degradation of tensile strength when exposed to intense UV rays over several years.
You'll find that Nylon 11 remains more ductile, which gets our thumbs up for long-term external applications.
