An erosion-indicating safety fitting having a fluid passage formed within for connection in-line with a pipe and a cage of interconnecting brea ch passages formed into the block and surrounding the fluid passage, particular ly at areas having a predicted risk of erosion. A pressure gauge, connected to the breach passages, registers a change in pressure to equal that of the pressur e in the fluid passage should the material between the fluid passage and one or more of the breach passages be eroded by the flow of particulate-laden fluid with in the fluid passage. The fitting can then be changed before compromising the safet y of personnel and the environment.
