Outside Seal and Fill Manual Connectors

The CTS Connect HO series seal on the outer diameter of smooth, rough or threaded features of a part, and allow filling or pressurizing through the fill port. They consist of a cam-driven piston that compresses the CTS-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.
Sealing ranges are from 0.030”-1.510” and standard threaded sizes (NPT, Metric, SAE, and BS). Sealing pressure from vacuum to 100 psig, depending upon the port surface finish. The HOF is the base model; the HOH features an ergonomic grip handle for operator comfort.
