Maximum working pressure 300 MPa (43,500 psi)

The range of SKF high pressure pipes covers most applications where there is a requirement to transfer oil at high pressure. They consist of a steel pipe with a steel ball fitted to both ends. Two swiveling connection nipples press these balls against the seating of the connecting hole and thus sealing against oil leakage.

  • Wide range of pipes
  • All pipes are pressure tested to 100 MPa (14,500 psi) over recommended working pressure
  • Special lengths (up to 4 m / 157 in) made on request 400 MPa versions available
  • Note: For safety reasons these high pressure pipes have a maximum recommended service life of 5 years.

Technical specifications

  • Maximum working pressure : 300 MPa (43,500 psi)
