Abstract: A line patch for use in repairing ruptures or leaks in fluid-carrying cylindrical pipes. One or more screw clamps, encircling a curved compression sleeve, are used to compress a resilient sealing member against a pipe rupture. For smaller diameter pipe (approximately less than one inch) applications, the compression sleeve has an inner lip which forms an abutment seat for the sealing member, which is an O-ring made of a resilient material such as rubber. In larger diameter pipe (greater than one inch) applications, the compression sleeve is a curved plate of constant thickness designed to approximate the outer curve of the pipe to be repaired, and the sealing member is a sheet of constant thickness resilient material. In the preferred embodiment, the screw clamp is a common hose clamp, the compression sleeves are made of metal, and the sealing members are made of rubber.
