Nylon Tube - Nylon Tubing
Manlon nylon tube is manufactured from vargin granules of : Nylon-6, Nylon-66, Nylon-11, Nylon-12, also known as Polyamide or PA6, PA66, PA11 & PA12.
Nylon Tube : Properties & Features
- High impact strength, High resistant to abrasion and Good functioning over wide range of temperature.- Tubes are semi flexible to super flexible and so a best substitute to copper and other metallic pipes
- Available in different grades - PA6, PA66, PA11 and PA12 tubings and in various colors.
- can be used for medium to high pressure to convey gas, oil, air and other fluids.
- Significant chemical, mechanical, thermal & electrical properties.
Nylon Tube : Advantages
- very cost effective- bendable and re-bendable easily
- flexible in nature (copper / Alumininium tubes are rigid basically)
- available in various colors such as white, black, blue, yellow, red, green etc.
Break down of the Specifications for Nylon 6, Nylon 11 and Nylon 12 - the most commonly used nylon materials for tubing:
Nylon 6 TubeGeneral Properties
High strength and stiffness
Excellent wear and abrasion resistance
Economical compared to other nylon grades
Moisture Absorption: High (3-4% in a saturated environment), which can lead to dimensional changes and affect strength
Chemical Resistance: Resistant to oils, fuels, and hydrocarbons, but less resistant to strong acids and bases
Temperature Range: -40°C to 100°C (-40°F to 212°F)
Applications
Pneumatic systems
Cable sheathing
Automotive fuel lines (when reinforced)
Limitations
Higher water absorption compared to Nylon 11 and 12
Moderate UV resistance (requires stabilizers for outdoor use)
Nylon 11 Tube
General Properties
More flexible than Nylon 6
Lower moisture absorption than Nylon 6 (approximately 0.8-1.2%)
Excellent chemical resistance, including resistance to strong acids
Good mechanical strength and fatigue resistance
Temperature Range: -40°C to 120°C (-40°F to 248°F)
Applications
High-pressure pneumatic and hydraulic systems
Automotive brake and fuel lines
Chemical transfer systems
Advantages
Lower moisture absorption ensures better dimensional stability
Superior impact resistance, especially in cold conditions
Cost:More expensive than Nylon 6
Nylon 12 Tube
General Properties
The most flexible and least moisture-absorbing of the common nylons (0.2-0.3%)
Excellent resistance to oils, greases, fuels, and many chemicals
High dimensional stability even in humid environments
Temperature Range: -40°C to 120°C (-40°F to 248°F)
Applications
Precision fluid transfer (e.g., medical, food-grade, and high-tech industries)
Automotive systems for fuel, brake, and hydraulic lines
Robotics and automation for flexible air lines
Advantages
Superior flexibility and fatigue resistance
Outstanding long-term durability in challenging environments
Cost:More expensive than Nylon 6
Comparision Table
Property | Nylon 6 Tube | Nylon 11 Tube | Nylon 12 Tube |
Strength | High | Moderate | Moderate |
Flexibility | Moderate | High | V.High |
Chemical Resistance | Good | Excellent | Excellent |
Moisture Absorption | High(3-4%) | Low0.8-1.2 | V.Low |
Temperature Range | -40 to 100 C | -40 to 120 C | -40 to 120 C |
Cost | Low | High | High |
Summary
Choose Nylon 6 for applications where cost is a primary concern and high strength is needed, but be cautious about its moisture absorption.
Choose Nylon 11 for better chemical resistance, moderate flexibility, and applications requiring lower moisture absorption.
Choose Nylon 12 for premium applications demanding high flexibility, dimensional stability, and resistance to challenging environments

Nylon Tube- Useful Guide Lines :
Do not forget to observe the rule of minimum bend radius rule for each size of nylon tube as different sizes have different bend radii.
Careful laying of tube will also give protection against abrasion. Possible effect of shrinkage will be compensated by allowing sufficient length of tube.
End fittings should be used as per best practice in the industry. While making end fitting connection, make it sure the tube ends are cut at right angles and the cross section of tube does not look elliptical. If this is not followed properly, leakage may occur at the fitting. Manlon tube fittings specially developed for nylon tubing are the best alternative.
Do not use tubes having damages such crack, kink, collapsed and uneven outside surface as all these reduce the quality and performance of tubes.
While using nylon tube for pressure purpose, always consider the temperature involved in the application as it can affect pressure rating of nylon tube.
If the fluid flow rate is high in the tube, it may cause to develop static energy which may lead to fire and so in such cases our manlon antistatic nylon tubing is recommended.
NOTES:
1) You can buy nylon tubes in various colors like Blue, Yellow, Orange, Black, Green, transperant, etc.
2) Nylon tubes are also known as PA Tubes, PA pipes,Pneumatic Tubes,Pneumatic pipes,Plastic Tubes, Plastic Pipes, Engineering Pipes, PVC Pipes, spring pipes,
plastic hose, plastic coil, high pressure pipes, pressure tubes, air pipe, air tubes,break pipes,air break tubes, non metallic tubes, etc.
