Abstract
The specification discloses a pipe joint which utilizes a spherically tapered coupling that mates spherically tapered pipe ends. Because of the spherical tapers, O-ring seals contained in the coupler do not engage the pipe ends until the pipe ends and coupling are seated to form the pipe joint. In one embodiment, a plastic ring or cap is made integral with each pipe end and acts as a sliding surface that allows ready joining of the pipe ends with the coupler.
