ABSTRACT:
A pipe coupler for interconnecting pipes and components together, for transferring bulk and fluid materials, and useful for connecting sections of pipe-end-to-end. The coupler connects grooved pipe to ground pipe, smooth pipe to grooved pipe or smooth pipe to smooth pipe. Also tees, valves, and pipe sections can be secured together. The coupler has an adjustable bail that can be adjusted to assure a tight seal despite any wear. The coupler also eliminates any gaps that may trap material and lead to cross-contamination of subsequent loads.
