  • Flexible Pipe Couplings

    Pipe strain can cause premature failure of pumps. This can frequently be absorbed by a flexible pipe coupling... but only if that pipe coupling is properly installed. Merely putting it into the line without any support, will not achieve any significant relief from the pipe strain. In order to protect the pump against the pipe strain, it must be anchored.
