Test results show that Turcon Roto Glyd Ring V runs with low frictional torque at all pressures from 0.5 MPa and above with low sensitivity to pressure increases from 0.5 to 20 MPa. It achieved a PV twice as high as other bidirectional seals and demonstrated 50% lower friction. Furthermore, wear of the seal and O-Ring was so low that it could not be measured.

Like other O-Ring activated Slipper Seals, the initial squeeze of the O-Ring ensures sufficient contact pressure between seal and mating surface to provide tightness at low pressure. With increasing system pressure, the O-Ring and the seal body direct have a contact force on the sealing surface to ensure sealing efficiency at all pressures.

Turcon Roto Glyd Ring V has a built in valve function. Valve ports are made from both sides of the Turcon ring profile to the space in the center, which is the lubricating groove. An elastomer ring is installed in the lubricating groove to prevent static leakage through the ports.
