ABSTRACT:
A well pipe connector for connecting a horizontal pipe outside a hollow well casing to a vertical pipe extending inside the casing. The connector has a first unit for external connection to the horizontal pipe which first unit is externally secured to the casing over an aperture therein with a hollow sleeve extending therethrough in alignment with the aperture. Extending into the aperture is an annular seat, the lower periphery of which rests upon the lower edge of the aperture with the remainder of the periphery being generally flush with the inner surface of said casing. A blind channel extends from the upper seat edge inside the casing downwardly at an angle outwardly toward the casing exterior. The second unit has an angled fluid passage with one end for connection to the vertical pipe and the other end extending through a generally planar flange adapted to be slidably received by the blind channel of said first unit. The flange is positioned at an angle with respect to said L-shaped passage such that insertion thereof into said channel to connect said first and second units will support said passage in alignment with said hollow sleeve with said one end in vertical downward position. Suitable resilient seals are provided between mating surfaces on said units.
