NNI 2-1/2" NH - NST Hydrant Swivel Thrust Buster Street T Pitot Flowtest Diffuser

This 2-1/2" NST heavy duty Fabricated (Yellow) Swivel T Diffuser is used to Flowtest and reduce the force of flowing water from fire hydrants or hose lines to control erosion and direct the flow pattern safely. It is recommended for all field-testing or water main flushing operations in which unsecured hoses are used to direct water flow. Available options are Straight version with Single and Dual Handles and 30° upbend.

It also has a replaceable pressure Pitot tube assembly with a quick connect Dual read Liquid Filed Psi/GPM Gauge assembly and a ball-bearing swivel hydrant adapter used to perform flow tests on hydrants and diffuse stream. Please note that there will be some pressure loss due to backpressure at the T bend.
