High pressure screw connect poppet & ball couplings made to the ISO 14540 Standard

Holmbury’s PSP & PSB Series screw to connect couplings are designed primarily for high pressure applications. They can be connected under low residual system pressures. The couplings are available with ball or poppet style valves.

  • Screw connect design eliminates brinelling
  • PSP offers poppet style valve
  • PSB offers ball style valve
  • Can be connected with low residual pressure in the hydraulic circuit
  • Bidirectional flow
  • Carbon steel with trivalent plating
  • Fitted with Polyurethane & Nitrile seals

Dust caps, plugs, plastic couplings and seal kits are available for the PSP & PSB Series

  • High pressure applications (Up to 720 bar (10440 psi) for PSB and 1000 bar (14500 psi) for PSP)
  • General industrial, construction plant, mobile equipment, demolition and agricultural industries
  • Hydraulic jacks
  • Torque wrenches
