  • (1) For O-rings for surface mounting, design the piping system in such a way that, when the internal pressure is applied, the outer circumference of O-rings is put in close contact with the outer wall of the groove; and when an external pressure is applied, the inner circumference of O-rings is put in close contact with the inner wall of the groove.
  • (2) When using an O-ring for surface mounting for an internal pressure, if the length of D is 30 mm or less, make the length approximately 0.2 to 0.3 mm longer.
  • (3) The groove dimensions are for reference.
