Unique & innovative products for the installation,
operation and maintenance of fire hydrants.

ASSURED FLOW SALES was founded with the creation of GRADELOK™and the intention of assisting utility professionals with the maintenance, operation and installation of fire hydrants.  Our goal is to make hydrant related work more productive, efficient and thorough.  We have carefully created all of our products to contribute to the realization of that goal.

GRADELOK™ was created in the field to address public safety, functional and aesthetic concerns of fire hydrants not set to grade.  GRADELOK™ is an adjustable offset that allows utility crews to set hydrants to grade the first time, eliminating the potential issues caused by improper installation.

HYDRA-EZE is our food grade anti-seize and thread sealing compound for fire hydrants.  This multifunctional lubricant is the environmentally conscious choice that outlasts and outperforms.

HYDRA-TAGS are our solid brass identification markers for hydrants and valves.  These durable tags ensure proper identification for the life of the product.  HYDRA-TAGS are rust and corrosion resistant and can be custom stamped to the customers specification.

N.I.S. BAGS are an economical method of identifying hydrants that are not in service.  These bright orange poly bags clearly state that the hydrant is NOT IN SERVICE.

NOZZLE SAVER prevents costly damage to fire hydrant hose nozzles due to excessive weight of construction meters and backflow preventers.  Constructed of schedule 40 aluminum pipe and solid brass connections the NOZZLE SAVER is both light and durable.

ASSURED FLOW SALES is committed to assisting utility workers by providing unique and innovative products that help make maintenance, operation and installation of fire hydrants more productive, efficient and thorough.  We are constantly looking to extend our product line to offer new products that support our commitment.
