NOTES:  1) The specified minimum bend radius is for minimal tube flattening.  2) The safety factor adopted sets the minimum bursting pressure at four (4) times the working pressure.  Please remember that the bursting and working pressure data listed are determined at 75°F. (24° Celsius)

Characteristics:

FrightProps ETHER based polyurethane tubing has the characteristics of an elastomer with good elongation and recovery along with many of the desirable properties of thermoplastics.  The temperature range is -40°F. to +180°F.  Polyurethane has good chemical and abrasion resistance yet is tough and flexible.

  • Most flexible
  • Kink resistant
  • Toughest
  • Broad range of chemical compatibilty
  • Excellent abrasion resistance
  • Excellent oxidation and ozone resistance

Hardness:

PU Polyurethane Tubing Hardness Rating: 

95 SHORE A (ASTM D 785)

Temperature Range:

PU Polyurethane Tubing Temperature Rating:
Minimum: -40°F - Maximum: 180°F.
Minimum: -40°C - Maximum: 82°C.
