Pipe Repair Coupling

NORMACONNECT® FLEX /FLEX E are axial non-restraint couplings. They are used for connecting metal pipes, stainless pipes, as well as concrete and plastic pipes. Sealing reliability is ensured even when NORMACONNECT® FLEX /FLEX E pipe couplings are mounted on pipes with or without a gap and on compensated pipes.

DIXON STRAUB OPEN-FLEX 1L COUPLING

Applications:
Suitable for repairing or joining pipes where access to the pipe end is difficult or not possible. The 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 Stc. C-219) or for permanent repairs or installation.
