Abstract: Natural gas pipe repair fittings and methods for using same allow safely welding a pipe repair fitting over a leaking natural gas service line “T” fitting. A bottom half and a top half are welded together to form a hollow cylinder having hemispherical ends with semicircular pipe notches in them. A hollow vertical pipe has one end welded over a pipe hole in the middle of the top half of the cylinder. A hemispherical cap is affixed to the opposing end of the vertical pipe. The cap has a cap hole in its top. A method for installing the natural gas pipe repair fitting by enclosing a leaking natural gas service line “T” fitting with the natural gas pipe repair fitting and welding the natural gas pipe repair fitting to the gas main line is also disclosed.
