HO (Outside Seal and Fill)

CTS-Schreiner Connect HO


  • Superior sealing capability without the risk of scratching the surface of the part
  • Large test/fill port holes for better conductance
  • Easy seal replacement
  • Long seal life

CTS-Schreiner Connect HO Connectors are designed to seal on the outer diameter of smooth, rough or threaded features of a part, and allow filling or pressurizing through the fill port.

The HO manual connectors (with and without grip handles) effectively seal on smooth, rough, or threaded circular features of a part. Manual connectors like the HO Connectors consist of a cam driven 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.
