OPEN-FLEX 3 ø 219.1 - 2032.0 mm
With joint, slotted casing, 2-part or 3-part, STRAUB-OPEN-FLEX can be mounted easily and quickly on existing pipes.
STRAUB-OPEN-FLEX pipe couplings have the same characteristics as STRAUB-FLEX couplings, but expand their possible uses.
The casings of the STRAUB-OPENFLEX product series can be hinged or available as 2-part or 3-part version. As a result, STRAUB-OPENFLEX couplings can be used for connecting pipes or repairs without removal of existing pipes.
STRAUB pipe couplings are made of the same or different materials depending on the diameter and size. The following overview shows the details. If you have any questions, please contact our application technology department.
