Floats for Threaded Rods
Ball Polypropylene
Ball Stainless Steel and Copper
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.
Stainless steel floats have excellent corrosion resistance and are also for use with oil.
Cylindrical and rectangular floats are self-tapping, except 4" dia. floats have a threaded hose connection.

Through-Hole Floats
Ball
The through-hole connection allows these floats to slide up and down a vertical float rod (not included). Use clamps (not included) to set them in a fixed position.
Stainless steel floats are more corrosion resistant than copper floats.

Hollow Corrosion-Resistant 3003 Aluminum Balls
- Yield Strength: Not Rated
- Hardness: Not Rated
- Temper: O
- Fabrication: Cold Rolled
Hollow construction reduces weight and allows these balls to float. They’re widely used in bearings and valves. 3003 aluminum stands up to outdoor use, as well as exposure to chemicals. It offers a good combination of strength, formability, and weldability.
