A pipe ring crimping tool providing significant mechanical advantage for applying force with a sufficient jaw opening and minimal external dimensions, minimal handle span and minimal handle length throughout the operation cycle. The tool is compact and lightweight to allow reach and access of the jaws into confined spaces. The tool utilizes a link and pin mechanism to translate the operator hand force exerted on the handles into a crimping force in a manner which allows for smooth application of operator hand force while increasing the crimping force as the pipe ring is compressed. The tool configuration by minimizing the handle spread, allows for single-handed operation. The tool or closely held two-handed operation. The tool includes a link mechanism designed to provide smooth crimping force and to preclude tool locking up and excess friction. The handles move laterally in opening the jaws to their maximum spread and are closed rotationally when crimping the pipe ring. |
