Heres a clean, practical breakdown

What is IS 446 Rubber Hose?

IS:446 specifies the requirements for rubber hoses with textile reinforcement and steel wire helix, suitable for suction and discharge of water and mild slurry.

Its much heavier and stronger than IS 444, especially for suction duty.

Construction (IS 446 Hose)

• Inner Tube: Natural / synthetic rubber
  (smooth, water & slurry resistant)

• Reinforcement:

  • Multiple textile plies

  • Steel wire helix (prevents collapse under vacuum)

• Outer Cover:
  Abrasion, weather & ozone-resistant rubber

Typical Specifications

• Size Range:
  25 mm (1) to 300 mm / 400 mm ID (and higher on request)

• Working Pressure:
  ~3.5 to 10 bar (depends on size)

• Vacuum:
