Floats for Threaded Rods
Cylindrical Polypropylene
Ball Polypropylene
Oblong Polypropylene
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. All are for use with water.
Polypropylene floats are lightweight and have good corrosion resistance.
Cylindrical and rectangular floats are self-tapping, except 4" dia. floats have a threaded hose connection.
