Trelleborg Sealing Solutions announced the launch of the new polytetrafluoroethylene (PTFE) based O-Ring energised single-acting rotary seal, Turcon Roto Glyd RingDXL.


With its design, 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 XploR range of NORSOK and API approved materials.


Eric Bucci, segment manager Oil & Gas Americas, said: “Trelleborg Sealing Solutions specialises in solving extreme oil and gas challenges, as evidenced by the new Turcon Roto Glyd Ring DXL.  Compared to traditional rotary seals, the Turcon Roto Glyd Ring DXL provides superior extrusion resistance and low friction characteristics in demanding high pressure drilling mud applications, extending service life and ultimately lowering overall costs for the operator.”


Turcon Roto Glyd Ring DXL is capable of handling pressures up to 70 MPa / 10,153 psi or speeds up to 5 m/s / 16.4 ft/s. Trelleborg recommends a maximum PV value 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/pumps, and hydraulic swivels.


Trelleborg said in a statement that through extensive internal R&D and customer testing, Turcon Roto Glyd Ring DXL has exhibited extended life and outstanding wear resistance in abrasive media applications.
