High Pressure Couplings : SP Series


Applications :

SP Series is High Pressure Poppet Type Screwed Couplings which are designed to withstand high pressures and pressure pulses. High pressure pulses create forces that act to separate the male and female couplings. With couplings that use ball-in-groove retaining mechanisms, the separating forces are concentrated mechanisms, the separating forces are concentrated onto a relatively small area - point contact of the balls - which can cause Brinelling (indentation of the balls into the groove). Brinelling will lead to leakage and eventually seizure of the coupling. Screwed couplings have a screw thread retaining mechanism that distributes the separating forces over a large surface area, thus eliminating brinelling. Therefore the SP Series are suitable for Mobile plant, agricultural implements and generalindustrial equipment.

Advantages :

  • Screw thread retaining mechanism to eliminate brinelling
  • Connection and disconnection can be performed even with low residual hydraulic pressure in the line.
