The Turcon® Glyd Ring® T's benefits are provided by the innovative functional principle of the trapezoidal profile cross section. The sides of the seal profile taper towards the seal surface. The profile can thus retain the robust and compact form typical of rod seals without losing any of the flexibility required to achieve a pressure-related maximum compression. Available in Turcon® or Zurcon® materials. This is a Custom Article Number with a Customer Specific Design.
