Quick Connector - Typ KI

For pressure- and vacuum tests on divers internal diameters of components


The innomatec connec ® KI type quick connector system seals drill holes and connects them to a control system. Oval, rough and cast surfaces with large sealing surface tolerance are sealed radially.

Function and operation

The innomatec connec ® KI type quick connector system can be inserted/driven into the drill hole manually or with an automatic tool. The quick connector is pneumatically operated with control air. The drill hole is sealed with a flexible rubber seal. The system is filled or sealed via the working connection.
After testing has been completed the control connection is vented, the seal de-pressurised and the connection can be removed/taken away. Depending on the diameter, working pressure or condition of the surface (oily etc.) the connection needs to be fitted with a slide barrier.

Sealed system

The innomatec connec ® quick connector system has excellent sealing properties ('helium-tight'). The rubber seal product life is designed to be suitable for series production. Rubber seals are very easy to change without tools.

Special designs

There are a number of special designs of the connection for specific applications with stroke limitation, sliding barriers, support hulls or special seals for specific environmental conditions. The dimensions of the connection can be adapted to the task for specific cases. Also for individual pieces. We look forward to your enquiry. Please use our checklist to do this.


We can deliver the following as accessories:

  • assembled screw connections for connection lines
  • mounted hand disc valve for controlling the connection
  • shut-off valve for the working fluid
  • blind plugs for working fluid
