ABSTRACT:
Plural spaced projections attached to the outer surface of a branch pipe of a tapping sleeve positioned on a main water line are disposed in contact with a rubber gasket also positioned on and disposed about the branch pipe. A two-piece split gland is also positioned about the branch pipe and engages a first surface of each of the projections. The split gland is adapted for coupling to the flange of a mechanical joint tapping valve by plural nut and bolt combinations for urging the gasket into intimate contact with a second opposed surface of each of the projections and the tapping sleeve's mechanical joint in forming a seal with the branch pipe. The split gland coupling allows for vertically orienting the tapping sleeve even when the main water line is not level, or horizontal, to facilitate tapping valve access via an extension pipe when the tapping sleeve is buried.
