Special steel body is tough against vibration and impact! Male and female thread end configurations are available. Low pressure loss characteristic suits hydraulic equipment applications.

  • Quenched special steel body! Powerful impact resistance, especially against impulses.
  • Valve is designed to suppress pressure loss, particularly suitable for hydraulic applications which need big fluid flow rates.
  • Automatic shut-off valves in both socket and plug prevent fluid spill out on disconnection. Easy to handle.
  • In addition to conventional female thread type, male thread types (male tapered thread, male parallel thread with 30˚ flare, and male parallel thread with 30˚ cone-seat) are newly added. Male thread types are designed especially for direct connection to hydraulic power units effectively.
  • Male parallel thread type complies with both metal seal and O-ring seal. (In case of O-ring seal, O-rings available in the market can be used.)
  • Optional HSP-DC Cuplas are available for die-casting machine applications with severe pressure variation.
  • The overall length of male thread type is shorter than that of female thread type plus conversion nipple available in the market.
