The Difference between Polyurethane and Nylon Tubing

Trying to decide whether to purchase nylon tubing or polyurethane hoses for your pneumatic application? Understanding the differences in materials will enable you to make the right choice and significantly improve system performance.
Polyurethane Tubing

POLYURETHANE HOSE OR NYLON TUBING?

Flexibility: While polyurethane is naturally flexible, nylon tubing can withstand repeated flexing better and longer.
Application: Polyurethane hoses are better suited to tight bending in and through equipment, such as in robotics and pneumatic control machinery. They are also commonly used in medium pressure applications such as solid, liquid and gaseous dispensing and fuel line and wire abrasion protection. Nylon, on the other hand, is recommended for hydraulic lines and refrigeration, air conditioning systems, fuel and oil transfer and chemical transport.
Durability: Although both materials have excellent resistance to abrasion from fuels, oils and abrasion, nylon tubing offers better heat and chemical resistance as well as supports higher working pressure.
Resistance: Nylon tubing has superior crack resistance and is an industrial standard for applications requiring greater resistance to chemicals, heat and working pressure.

ADVANTAGES OF NYLON TUBING:

  • High compressive strength
  • Rigidity, abrasion resistance 
  • Can withstand higher temperatures
  • Good friction coefficient
  • Great resiliency
  • Inherent wear resistance
  • And low cos
