Fitting

A gripping assembly for a pipe fitting comprising:

• an outer crown comprising a plurality of outer teeth;
• an inner crown comprising a plurality of inner teeth nested with the plurality of outer teeth;
• a ramp defining an angled ramp surface;
• and
• a grip ring defining an angled ring surface;
• wherein:
• the gripping assembly defines a gripping axis extending centrally through the outer crown, the inner crown, the ramp, and the grip ring;
• the outer crown is configured to rotate the outer teeth against the inner teeth to bias the inner crown axially against one of the ramp or the grip ring;
• and
• the angled ring surface of the grip ring is configured to slide along the angled ramp surface of the ramp to bias the grip ring radially inward relative to the gripping axis.

A pipe fitting comprising:

• a fitting body defining a first fitting end, a second fitting end opposite the first fitting end, and a fitting bore extending from the first fitting end to the second fitting end, the fitting bore defining a fitting axis and at least one axial guide rib;
• and
• a gripping assembly arranged at least partially within the fitting bore, the gripping assembly comprising:
• a ramp defining an angled ramp surface;
• and
• a grip ring defining an angled ring surface, wherein the angled ring surface of the grip ring is configured to slide along the angled ramp surface of the ramp to bias the grip ring radially inward relative to the fitting axis;
• wherein one of the ramp and the grip ring defines at least one axial groove, each axial groove configured to slidably receive a corresponding axial guide rib therein.
