Straub Open-Flex 1L Couplings
Not pull-out resistant.
Ensure that pipes are properly anchored and supported.
Applications:
Straub Open-Flex 1L couplings are suitable for repairing or joining pipes where access to the pipe end is difficult or impossible.
This unique wrap-around design differs from similar type repair products because the installation or repair is permanent due
to the unique flexible lip seal gasket design. Open-Flex couplings will also act as an expansion joint.
Straub Open-Flex
couplings do require the pipes to be properly anchored and restrained as they are not pull-out resistant like the Straub Grip-L
couplings.
Use Straub Open-Flex couplings to replace bolted sleeve type couplings (AWWA Std. C-219) or for permanent
repairs or installation.
