A novel terminal outlet fitting for use in sprinkler systems with a standard split-sleeve sealing coupling engaging the fitting and a standard grooved end pipe, in order to provide an oriented pressure outlet to which a sprinkler head may be fitted. The fitting provides a high efficiency low pressure drop, streamlined flow so that effective sprinkler discharges is achieved. The process avoids the previously labor intensive high cost welding attachment of a connection outlet over a hole drilled through the pipe wall, characterized by poor flow characteristics, and the need to provide a separate pipe end closure and effects a material saving in piping. The novel fitting and its method of use effects significant direct cost savings, in material and on-site labor, and provides a more effective sprinkler system.
