Abstract
Stab-type pipe fittings capable of being inserted onto plastic pipes are provided. The pipe fittings have an outer casing with pipe ports, a hollow inner casing positioned within the outer casing, a pipe gripper and stiffener positioned within the inner casing. The pipe ports have an elongated lip that straightens a pipe inserted into the fitting. The stiffener provides a multi-compression seal to facilitate the leak proof connection.
