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 Cylinder Floats

Polypropylene floats are lightweight and meet NSF/ANSI 61 standards for safe use with drinking water.

Cylindrical floats are all self-tapping except those with a 4” diameter, which have a threaded hose connection.

Compact Metal Float Valves

Smaller than other float valves, these are sized for containers with limited space. Use them to control water levels in processing tanks and cooling towers.

NPT Male × Threaded Inlet Connection × Discharge Outlet

NPT Male Inlet × Discharge Outlet

Valves with a discharge outlet release contents into your tank; the outlet is unthreaded.

Horizontal-Mount Float Switches for Chemicals


Switch	Switch with Splash Guard

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 chemical level in your tank reaches the float.

Splash Guard—Switches with splash guard minimize false switch activation caused by splashing liquid.

Horizontal-Mount Float Switches for Fuels and Oils


Style D

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.

Horizontal-Mount Hazardous Location Float Switches for Fuels and Oils


Style A

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations. Mount them through a tank wall. All are rated NEMA 4 for protection from washdowns. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” or from “on” to “off”.

Switches with a stainless steel body are more corrosion resistant than switches with a brass body.
