Product Description

Product Lines: Hydraulic Flange Spreader

  • Flange spreaders should be used in pairs to provide even spreading force
  • Standard 60° wedge is suitable for most flanges; 30° “thin” and 60° “blunt” wedges are optional
  • Max working pressure 700 bar (10, 000 psi)
  • Uses a standard 3/8″ high flow coupler
  • Use HFS3A for applications where total thickness of flanges and max. spread gap is 76,2 mm or less, and flange bolts are a min. of 17,5 mm diameter.
  • Use HFS6A if total thickness of flanges and max. spread gap is 152,6 mm or less, and flange bolts are a min. of 20,7 mm diameter.

Think Safety

Manufacturer’s rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!
