Flexible Coupling Marine

The Straub-Flex coupling for marine vessels will join virtually any plain-ended pipe, including pipe made from different materials. Straub-Flex couplings install quickly, safely and economically and can accommodate pipe system expansion and contraction as well as angular deflection. Straub Open-Flex couplings offer all the Straub-Flex benefits in a split-coupling version that allows for repairs in service pipelines. Leaks due to faulty weld joints, pitting holes and short cracks can be temporarily or permanently repaired with minimal down time. The split gasket design wraps around the pipe with no disassembly.

Used for: Joining and repairing pipes of all types in a marine environment. Internationally approved fire-resistant couplings are available wherever fire protection is needed.
