CO (Connect Outside)

CTS-Schreiner Connect CO


  • Superior sealing capability without the risk of scratching the surface of the part
  • Automated sealing to minimize operator fatigue and injury
  • Large test/fill port holes for better conductance
  • Easy seal replacement
  • Long seal life

The CTS-Schreiner Connect Outside Diameter (CO) pneumatic connectors effectively seal on smooth, rough, or threaded circular features of a part. These pneumatic connectors consist of an air-driven internal piston that compresses the CTS-Schreiner proprietary seal material against the surface of the part, creating a tight seal that meets all test pressure requirements regardless of surface shape or finish.
