Trelleborg announces new rotary seal for high pressure oil & gas applications

Trelleborg Sealing Solutions has launched a new polytetrafluoroethylene (PTFE) based O-Ring energized single-acting rotary seal, the Turcon Roto Glyd Ring DXL. This seal is designed to meet the demands of high pressure rotary applications within the oil and gas industry.

The product 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 the company’s proprietary XploR range of NORSOK and API compliant materials.

David Brown, Trelleborg Sealing Solutions Global Director – Lead Group Oil & Gas, said, “Trelleborg Sealing Solutions specializes 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. The value added benefits of the Turcon Roto Glyd Ring DXL allow our customers to provide innovative solutions and equipment to their customer base.”

The product is capable of handling pressures up to 10,153psi (70Mpa) and speeds up to 16.4 ft/sec (5m/sec). 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 / pumps, and hydraulic swivels. Through extensive internal R&D and customer testing, the product has exhibited extended life and outstanding wear resistance in abrasive media applications.
