Floats for Threaded Rods



Connect these floats to threaded float rods (not included). Use them to replace an existing float or combine with rods and float valve bodies (not included) to build a float valve.
Polypropylene floats are lightweight and meet NSF/ANSI 61 standards for safe use with drinking water.
Cylindrical and rectangular floats are all self-tapping except those with a 4” diameter, which have a threaded hose connection.
