A. The SharkBite system increases ease of use while decreasing the time and effort needed to connect water distribution pipe. The pipe is inserted into the fitting and held in place by several metal "teeth" and a durable grab ring. The pipe then passes through a specially formulated O-ring that compresses between the wall of the fitting and the tube to secure the joint. The joint can be disassembled only with a SharkBite demount clip or tong.
