The Turcon Glyd Ring T is a very effective and reliable low frictional seal. The double acting Turcon Glyd Ring T is a combination of a Turcon-based slipper seal and an energizing O-Ring. It is produced with an interference fit which together with the squeeze of the O-Ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-Ring is energised by the fluid, pushing the Turcon Glyd Ring T against the sealing face with increased force.
