  • Publication number: 20040169371
    Abstract: A novel speed lock fitting with a threaded drive pin that obviates any shock or vibration to the piping system, and can also be used in tight spaces where no one could practically swing a hammer. Assembly of the connecting fitting with drive pins as shown in the illustrations can be accomplished with a cordless electric driver or hand tool such as a wrench or socket wrench. Disassembly is then simply the reverse of assembly. The drive pin can be applied with greater net force to the pipe wall, thus making it a good choice for standard and heavy wall pipe.
