Trelleborg Turcon® Glyd Ring® T is a double-acting O-Ring energized piston seal for dynamic applications, available in a range of materials (e.g. Turcon® and Zurcon®). Fully interchangeable with the earlier Glyd Ring® T, it provides very good static leak tightness and good resistance to extrusion, also demonstrating excellent friction characteristics with no stick-slip, minimal break-out force and high wear resistance
