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.
Stainless steel floats have excellent corrosion resistance and are also for use with oil.

Floats without Connections
![](/prerenderstable/mvPRE/contents/gfx/imagecache/283/2833k36-@halfx_636970543585401703.png?ver=imagenotfound)
These floats are untethered by a float rod so they can float freely in your tank.
316 stainless steel floats are more corrosion resistant than 304 stainless steel floats.
