The Rigid Aluminum Diffuser is a great way to test hydrant flow without destroying surrounding property. Because of its large cone shape the water is dispersed in a wide pattern. There is also an opening in the unit before the water is diffused for readings using pitot tubes or other devices. Great for use where different thread patterns are used since you can quickly change out the swivel coupling to the desired thread pattern needed.

• Change out couplings to different thread quickly
• Opening for taking flow readings with Pitot Tube
• Baffles easily replaced if damaged with rocks and debris
• Diffuses flow to 5 feet at 1,200 gpm.
