CTS Connect - Air Actuated & Manual Connectors Manual Connectors The CTS ConnectTM line of manual connectors are designed for durability and superior wear. These rugged connectors are designed with the operator in mind, featuring ergonomic actuating levers and optional comfort grip handles. Air Actuated Connectors CTS ConnectTM air actuated internal or external connectors effectively seal on smooth, rough or threaded circular features of a part. The connectors consist of an air-driven internal piston that compresses the durable proprietary seal material against the surface of the part. This creates a tight seal that meets all test pressure requirements, regardless of surface shape or finish
