Abstract:
1. A reusable, unitary tool for purging fluid from a fluid flow pipe system or portions thereof, the reusable, unitary tool having an interior channel of substantially uniform diameter and comprising: an input portion configured with a male connector nozzle for unthreadedly insertively coupling to a complementary female connecting end of a source of positively-pressurized flow of air/gas; a flow control portion configured to regulate an amount of the positively-pressurized air/gas flow communicated through the substantially uniform diameter interior channel; a pressure measurement device configured to indicate the amount of pressurized air/gas flow communicated through the substantially uniform diameter interior channel in accordance with the flow control portion; and an output portion for introducing the regulated amount of pressurized air/gas flow communicated through the substantially uniform diameter interior channel into the fluid flow pipe system or portions thereof, the output portion including a pressure-fitted slip coupling portion with an internal unthreaded arrangement that is configured to temporarily, releasably, and sealably slidably engage an exterior, unthreaded surface of a substantially cylindrical open pipe end portion of the fluid flow pipe system to enable the regulated pressurized air/gas flow to purge fluid from the fluid flow pipe system or portions thereof.
