Abstract
A pipe coupling system includes first and second polymeric, thermoplastic pipes secured to each other by a pipe coupling. The pipe coupling includes a mechanical sealing surface adapted to receive a mechanical seal, a fusion seal, or both. The pipe coupling includes a pipe coupling body with an outer surface and a first end and an oppositely positioned second end. First and second respective threads are respectively defined about the first and second ends. A nut is used in the pipe coupling system when the mechanical seal is used to join the pipe first ends to seal against the coupling inner surface. A mechanical capture ring is also included, which defines a central aperture having inwardly angled engagement prongs that are sized to capture the respective first ends of the pipe. The engagement prongs are configured to each include a sloping face.
