Abstract
An anti-rotational push to connect fitting includes a housing defining an internal cavity, the internal cavity having, at least in part, a non-circular shape. The housing has a conduit receiving region having an inwardly oriented wall. A seal is positioned in the housing adjacent to the conduit receiving region. A grip ring support is positioned in the housing adjacent to the seal. The grip ring support has a transverse flange having an inner peripheral edge and an outer peripheral edge and a longitudinal wall extending from the flange spaced from the inner and outer peripheral edges to define gaps between the longitudinal wall and a wall of the housing and inwardly of the longitudinal wall. A grip ring is positioned adjacent to the grip ring support and is seated on an end of the wall. The grip ring has a non-circular shape configured to cooperate with the housing internal cavity and the grip ring support. The grip ring has a peripheral portion that seats on the longitudinal wall and a series of circumferentially positioned, inwardly projecting flexible, angled fingers.
