GWI type quick connector system
Use
The innomatec connec ® GWI type quick connector system seals internal threads or connects them to a control system. Sealing surfaces as well as test pieces are sealed in an axial direction.
Function and operation
The innomatec connec ® GWI type quick connector system is screwed hand-tight to the test piece's connection until the seal sits on the counter piece. The quick connector guarantees a pressure-tight connection up to 340 bar if the system is pressurised. Testing can now take place by feeding the pressurised medium. Release the pressure after testing. The quick connector can be manually unscrewed again without tools.
Sealed system
The innomatec connec ® quick connector system has excellent sealing properties ('helium-tight'). The O-ring's product life is designed to be suitable for series production. O-rings are very easy to change.
Special designs
There are a number of special designs of the connection for specific applications or 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
