Abstract: An architecture is presented that provides a tool for uncoupling a breakaway coupling used in a flow line system used with liquid anhydrous ammonia. The compression tool comprises a first member and a second member for engaging the breakaway coupling. The first and second members are secured together with a fixed element and an adjustable element. The adjustable element is typically a threaded rod that allows a user to adjust the bottoms of the first and second members so that they adjust inward creating a sufficient force to overcome a spring holding the breakaway coupler together.
