Non-tension resistant pipe coupling

STRAUB-OPEN-FLEX-2

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.
