A further development of the Turcon® Glyd Ring® T provides improved leakage control and better resistance to extrusion. It is a double-acting O-Ring energized rod seal for dynamic applications that can be installed in grooves to ISO 7425. It offers low friction with no stick-slip, minimal break out force and high wear resistance.


Turcon®glyd ring®T is a further technical development of Turcon®glyd ring®. it is fully interchangeable with earlier glyd ring®seals in all new applications.


The main benefits of the patented seal are provided by the innovative functional principle of the trapezoidal profile cross section. The sides of the seal profile tapers towards the seal surface. The profile can thus retain the robust and compact form typical of piston seals without losing any of the flexibility required to achieve a pressure-related maximum compression.


The edge angle of glyd ring®T permits an additional degree of freedom and enables a slight tilting movement of the seal. The  maximum compression is thus always shifted towards the area of the seal edge directly exposed to the pressure. on the low-pressure edge of the seal, glyd ring®T exhibits only zones with neutral strains without compressive or shearing loads, thus effectively reducing the danger of gap extrusion.



Pressure: up to 60 MPa

Speed: up to 15 m/s

Frequency: up to 5 Hz.

Temperature: -45 °C to +200 °C depending on O-ring material 

Media: Mineral oil-based hydraulic fluids, flame retardant hydraulic fluids, environmentally friendly hydraulic fluids (bio-oils), phosphate ester, water, air and others, depending on the seal and O-ring material compatibility see Table 68. 

Clearance: The maximum permissible radial clearance Smax is shown in Table 69 as a function of the operating pressure and functional diameter.
