The connector features a dual seal design with independent activation of seals and taper locks for efficient installation and seal testing. STATS Connectors have an extensive track record spanning over 15 years, with 100% leak-free service. Designed in accordance with recognised industry standards and guidelines, the Connector components are compatible with a wide range of fluid types and flow conditions. All Connector components are coated to provide protection for use in hostile operating environments.

Connector Configurations

  • Flanged outlet for connecting plain-end pipe to a pre-flanged termination, mis-alignment flange interface available
  • Coupling for connecting plain-end pipe to plain-end pipe
  • End Cap for capping plain-end redundant pipework

Connector Applications
