Abstract
A compression fitting including a body portion defining a first end portion, and a grip ring assembly with a grip ring disposed within the first end portion, the grip ring being movable from a first axial position to a second axial position with respect to the longitudinal center axis of the first end portion, wherein the grip ring is disposed in the first axial position when the compression fitting is in a loosened configuration, and in the second axial position when the compression fitting is in the tightened.
Claims21
A compression fitting comprising:
- a body portion defining a first end portion;
- and
- a grip ring assembly configurable in a loosened configuration and a tightened configuration, the grip ring assembly comprising a grip ring disposed within the first end portion, the grip ring being movable from a first axial position to a second axial position with respect to a longitudinal center axis of the first end portion,
- wherein:
- the grip ring is disposed in the first axial position when the grip ring assembly is in the loosened configuration, and the grip ring is disposed in the second axial position when the grip ring assembly is in the tightened configuration,
- the grip ring is movable from a first radial position to a second radial position with respect to the longitudinal center axis of the first end portion, and wherein the grip ring is disposed in the first radial position when the grip ring assembly is in the loosened configuration, and the grip ring is disposed in the second radial position when the grip ring assembly is in the tightened configuration, and
- the grip ring assembly further comprises a cam ring disposed adjacent the grip ring, wherein the cam ring is movable from a first axial position to a second axial position with respect to the longitudinal center axis of the first end portion, and the cam ring is rotatable from a first circumferential position to a second circumferential position with respect to the longitudinal center axis of the first end portion.
