20080309067 | Repair pipe fittings - Disclosed is a pipe fitting specifically designed for repair applications called a Repair Pipe Fitting. One or more of the arms (inlets or outlets) of a Repair Pipe Fitting is longer than the corresponding arm on a standard pipe fitting, so that connecting pipes that have been cut to remove a standard pipe fitting do not have to be extended to install a Repair Pipe Fitting. Repair pipe fittings are best suited for use with plastic pipe, where joints are sealed with cement, although Repair Pipe Fittings may also be used with metal pipe, where joints are sealed with welds or threads. Repair pipe fittings may be sealed using the same sealing method as used by the original fittings, such as cement for plastic fittings and pipes. Repair pipe fittings may also be sealed using a non-permanent sealing method such as compression caps and gaskets. | 12-18-2008 |
