Rotating sealed coupling for flexible externally threaded conduit - uses two-part connector, one part screwing onto conduit thread then snap fitting into other part to allow relative rotation

摘要

A tubular collar is threaded at one end and at the other end has a projecting rim with a shouldered edge which can be click fitted into a mating slot in the other half of the coupling, permitting free rotation of the two halves relative to each other. A sealing ring fits under the projecting rim and the end of the conduit butts against this ring. The second part of the connector is threaded internally, having trapezoidal thread profiles which lock into the thread profile on the exterior of the flexible conduit. The second part is screwed onto the conduit then click fitted to the other half of the connector.
