ABSTRACT:
A sprinkler apparatus including a manifold is used with a nipple and a union. The manifold includes a pipe section and at least one port. There is a fitting on the port. The nipple has a proximal and distal end. A fitting is located at the distal end of the nipple. One or more radially extending projections may be positioned around the circumference of the nipple. The fitting on the distal end of the nipple may form a water-tight seal with a fitting on a valve without tightening with a wrench by mating projections and indentations and applying a torque to the union. The union includes one or more indentations that may align with and mate with the projections to allow the union to slide over the nipple. The union has a fitting. The fitting on the union corresponds to and engages the fitting on the port.
