FlatFace coupling NW5-G1/8 FF

The FlatFace design reduces leakage when connecting and disconnecting the coupling.

The clean design also reduces the possible degree of contamination in area of the media and on the outer surface.

Due to the materials used, the coupling is ideally suited for use in aggressive environments and for cleaning with intensive agents, such as in the food processing industry, pharmaceutical and chemical production. The construction enables simple one-handed operation when positioning and coupling.
