Next-generation hose types can cut down on "hose fatigue" that can result in failures. Hose materials that are incompatible with certain chemical compounds, susceptible to cracks during operation or prone to rupture when handling particle-laden fluids should not be used. Hose materials that can eliminate leakage concerns include:

  • Natural rubber: Ideal for use with diluted acids and alcohols, with excellent abrasion resistance
  • Ethylene propylene diene monomer: Possesses a high chemical resistance to concentrated acids, alcohols and ketones
  • Hypalon: Strongly resistant to chemicals, temperature extremes and ultraviolet light
  • Buna-N: Highly wear resistant to oil products
