S Series

S Series

Mechanical strength and the impossibility of an accidental release of the male from the female makes very safe the use of these screw-on couplings: they are very suitable in heavy hydraulic applications either for adverse environment conditions or for high work pressures. Fields of application: industry, iron industry, oil plant, earth moving machinery and similar service vehicles.

  • Interchangeability: according to MB internal standard
  • Shut-off system: poppet valve
  • Latching system: screw-on
  • Connection: screwing-on the male’s sleeve
  • Disconnection: screwing-off the male’s sleeve
  • Connectability: allowed under residual pressure
  • Disconnection under pressure: allowed under residual pressure
  • Threads: BSP – NPTF
  • Sizes: 1/4", 3/8”, 1/2”, 3/4”, 1”, 1 ¼”, 1 ½”, 2”, 2.1/2”, 3”
  • Materials: Female in carbon steel, sleeve and male in high grade carbon steel, steel hardened valve
  • Surface treatment: zinc plating and Cr III passivation Springs in C72 steel
  • Seals: standard NBR, on request VITON
  • Antiextrusion rings: PTFE
  • Working Temperatures: NBR -20°C +100°C VITON -15°C +140°C

For temperature exceeding this values, the quick-release couplings will be supplied with all components in steel.
