Abstract: A device for protecting a portion of a pipe is provided. The device comprises a disk-shaped base having a proximal base surface and a distal base surface. An annular connector extends proximally from the base and has an interior connector surface and an exterior connector surface and a threaded engagement portion configured for threadably engaging the series of pipe threads. The device further comprises a ridge extending distally from at least a portion of the outer edge of the distal base surface. The ridge has a ridge height, an outer ridge surface and an inner ridge surface. The device also comprises a plurality of ribs extending distally from the distal base surface and radially inward toward the base axis from the inner ridge surface.
