International Classification:

F16L 37/088

Abstract:

A push to connect fitting includes first and second fitting components, a sealing arrangement, a gripping arrangement, and a colleting ring. The first fitting component has an outboard end that is adapted to receive a conduit end. The second fitting component is joined to the first fitting component to define an interior cavity. The sealing arrangement, disposed in the interior cavity, seals one of the first and second fitting components with an outer surface of a conduit end when the conduit end is inserted into the outboard end of the first fitting component. The gripping arrangement is disposed in the interior cavity, and the colleting ring is disposed in the interior cavity and has an inboard end surface engaging an outboard end surface of the gripping arrangement.

International Classification:

F16L 19/06

Abstract:

A conduit fitting preassembly includes an annular fitting component and at least a first conduit gripping device. The annular fitting component has an interior wall extending axially from a forward end to a rearward end, and a first projection extending radially inward from the interior wall. The first conduit gripping device is received within the annular fitting component and includes a second projection extending radially outward of an outer surface of the first conduit gripping device. The first projection includes an outward tapered rear surface and the second projection includes an inward tapered front surface. The rear surface of the first projection is radially aligned with the front surface of the second projection, such that when the first conduit gripping device is in a forward-most position, the first projection interlocks with the second projection to prevent axial withdrawal of the first conduit gripping device from the annular fitting component.
