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.
Claims1
A speed lock pipe fitting for a pipe comprising a threaded drive pin, the pin having a hex head portion, a threaded portion and a tapered portion, wherein the pin head is adapted for driving with a conventional driver or wrench to screw the threaded portion into a correspondingly threaded pin hole in the fitting, and whereby the tapered portion of the pin is drawn up tight against the pipe wall to deform a wall of the pipe.
