  • Patent number: 3944260
    Abstract: Repair fittings are provided sealing ruptures or leaks in existing piping systems. The fittings are economical to produce and can be simply installed to provide effective and reliable leak protection. The fittings are of the gasket type and include a pair of substantially identical housing halves which can be fixedly attached to enclose a piping coupling and sections of the accompanying piping. The gaskets are positioned in grooves formed in the surface of each housing half. In assembly, the gaskets compressively mate to provide a fluid tight seal between the two halves with multiple fluid tight seals being formed around the pipe sections encompassed by the fitting.
