Trelleborg Sealing Solutions has announced the launch of a new polytetrafluoroethylene (PTFE) based O-ring energised single-acting rotary seal, the Turcon Roto Glyd Ring DXL. This seal is specifically designed to meet the demands of high pressure rotary applications within the Oil and Gas industry.
The Turcon Roto Glyd Ring DXL provides improved dynamic sealing efficiency and reduced friction by balancing the contact force on the dynamic lip under all service conditions, allowing for superior extrusion resistance and low torque. The seal is available in Trelleborg Sealing Solutions proprietary XploR range of NORSOK and API compliant materials.
It is capable of handling pressures up to 70 MPa/10,153 psi and speeds up to 5m/s/16.4 ft/s. Trelleborg recommends a maximum PV value of up to 48 (MPa x m/s)/1.4m (psi x ft/min) for optimal performance. These operating conditions are typically encountered in downhole tool, rotating control devices, hydraulic motors and pumps and hydraulic swivels.
