A fitting for repairing a leaking polymer pipe is provided. The fitting includes a first housing and a second housing that are sized to fit about the pipe. The first housing includes a first coil configured to increase in temperature in response to the application of an electrical current to fuse the first housing to the second housing and the pipe. The second housing includes a second coil on a first end and a third coil on an opposing end. The second and third coils configured to increase in temperature in response to the application of electrical current to fuse the second housing to the pipe. The fitting further includes a first seal coupled to the first housing and a second seal coupled to the second housing. The first and second seal forming a seal that prevents gas pressure from the pipe from interrupting the fusion process.
