A polypropylene float makes these switches buoyant even in viscous liquids.

Floats

Floats for Threaded Rods

Connect these floats to threaded float rods.

Floats for Chemicals

Made of polyethylene, these floats can be used with chemicals, salts, and caustic fluids.

Float Valves

Brass Float Valves

Use these float valves with water.

Extra-Compact Plastic Float Valves

Control water levels in spaces where a rod and lever won’t fit; these float valves have an internal float and connect to your pipe.

Compact Metal Float Valves

Smaller than other float valves, these are sized for containers with limited space.

PVC Float Valves

These float valves have a temperature range of 35° to 110° F.

Polypropylene Float Valves

Able to withstand higher temperatures than PVC float valves, these valves have a temperature range of 35° to 175° F.

Compact Plastic Float Valves

Smaller than other float valves, these are sized for containers with limited space.

Compact Float Valves for Food and Beverage

Smaller than other float valves, these are sized for containers with limited space.

Compact Float Valves with Plastic
Reservoir for Food and Beverage

Commonly used in ice-making machines, these valves have floats that rest inside a clear plastic reservoir.

Polypropylene Balls

Because this polypropylene resists swelling when exposed to water, it’s often fabricated into containers and parts for laboratory equipment.

Flotation Devices

Life Preserver Rings

Throw flotation rings into the water for emergency rescues.

High-Visibility Life Vests

Vests are fluorescent yellow with reflective stripes to meet ANSI/ISEA 107 standards for high-visibility clothing.

Life Vests

These vests have features such as snag-resistant belts and automatic inflation for specialized work near the water. They are international safety orange with reflective panels to draw attention.
