T-LON PTFE Backup Rings are available in two styles; 28774 - split ring and 27595 - solid ring |
T-LON PTFE Back-up Rings are designed to prevent extrusion in rubber O-ring sealing systems.
The amount of this extrusion is affected by O-ring hardness, operating temperature,
operating pressure and clearance of the mating surface.
Increased Pressure: The use of Back-up Rings should be considered for systems with operating pressure above 2000 PSI. At these pressures the mechanical forces applied to the O-ring may cause extrusion of the O-ring into the clearance gap. Operating temperature: The use of Back-up Rings should be considered for elevated temperatures greater than 160°F (71°C). The physical and mechanical properties of O-rings may be affected at these temperatures, increasing the risk of extrusion into the clearance gap. Industrial Trends: Today's fluid power systems continue to move toward higher pressures and temperatures. T-LON PTFE Back-up Rings should be considered as a reliable component to achieve satisfactory system performance. |
