Floats without Connections
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.

Horizontal-Mount Float Switches for Fuels and Oils
Install these switches into a threaded connection in your tank wall from outside the tank. They activate process equipment such as pumps or motors when the diesel fuel, hydraulic fluid, or oil level in your tank reaches the float. Choose switches with a metal body for durability in harsh conditions.
Switch with splash guard minimizes false switch activation caused by splashing liquid.
