1. A pipe fitting comprising:
a fitting body defining an inner surface, an outer surface, a first fitting end, and a second fitting end, the inner surface defining a channel extending from the first fitting end to the second fitting end, a fitting axis extending centrally through the channel, a portion of the inner surface defining a tapered region tapering towards the first fitting end, the channel configured to receive a pipe therein; and
an engagement assembly comprising:
a metal grip ring received in the channel, the metal grip ring defining a ring body and a tooth extending inward from the ring body, the engagement assembly configured to slide along the tapered region; and
a substantially C-shaped guide ring defining a guide outer surface, a guide inner surface, and a substantially C-shaped slot defined between the guide outer surface and the guide inner surface, wherein the ring body of the metal grip ring engages the substantially C-shaped slot, and wherein the substantially C-shaped slot defines an open first slot end and an open second slot end opposite the open first slot end;
wherein the tooth defines a proximal edge coupled to the ring body and a distal engagement edge distal to the ring body, the tooth defines a first width at the distal engagement edge and a second width at the proximal edge, and the first width is greater than the second width; and
wherein the tooth is oriented substantially perpendicular to the fitting axis in a pre-assembled configuration prior to receiving the pipe in the channel.
