Hydraulic tools & reference
Free reference tools for hydraulic specification — pressure conversion, hose dash sizes and thread identification.
Thread identifier
Work from taper, thread angle and seat to a fitting family — JIC, ORFS, BSP, metric DIN, NPT or Komatsu.
Pressure converter
psi, bar and MPa. The same hose is specified in all three depending on whose datasheet you are reading.
Dash size chart
Dash number to inches and millimetres, with the two caveats that cause most ordering mistakes.
