  • Combination mechanical/fusion pipe fitting with push connect coupling arrangement
    Patent number: 9611958
    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.

  • Electrofusion joining control device
    Patent number: 6680464
    Abstract: A piping system that includes a plurality of pipe made of thermoplastic material, a coupling and an arrangement for securing the pipe to the coupling. The coupling is configured so that either a fusable seal or mechanical seal can be used with the coupling to connect the pipe to the coupling with an electrofusion joining control device. Preferably, the pipe and coupling are made of thermoplastic material.
