Glyd Ring® RG23 is produced with an interference fit which together with the squeeze of the O-Ring ensures sealing effect even at low pressures. At higher system pressures, the O-Ring is energized by the fluid, pushing Glyd Ring® against the sealing face with increased force. Besides good static sealing the wide, shallow chamfers provide generous lubrication of the dynamic contact area in reciprocating applications. Available in Turcon® or Zurcon® materials. The O-Ring is not included with this item.
