CO Series External Seal Air Actuated Connectors

The CTS Connect CO series pneumatic connectors effectively seal the outer diameter (OD) on smooth, rough, or threaded circular features of a part. These pneumatic connectors consist of an air-driven internal 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.

Standard sizes range is 0.30” OD to 3.032” with larger sizes available as a custom option. Rated for low pressure vacuum to test pressure of 500 psig.
