Hollow Stainless Steel Magnetic Float Balls

A floater ball, or float ball, is a hollow buoyant sphere or oval-shaped device that rises and falls with liquid levels inside a tank or chamber. In industrial applications, stainless steel float balls are used to control float valves, activate pumps, shut off vacuum systems, or trigger level sensors depending on liquid height.

Round magnetic float balls are available in diameters of 1-1/2", 2", 3", 3-1/2", 4", 5", 6", 7", 8", 10", 12", and 14". Oblong magnetic float sizes include 2x6", 3x5", 3x6", 3-1/2x12", 3-1/2x20-1/2", 7x12", 7x16", and 9x14". Custom sizes are also available upon request.

Magnetic float balls are manufactured from 304 stainless steel, which is the most common grade, or 316 stainless steel for enhanced corrosion resistance in more aggressive chemical environments. Other materials can be made available upon request. All options offer superior durability compared to plastic float alternatives in industrial settings.

Yes, custom threads and fittings are a core capability. Common thread specifications include 1/4-20, 3/8-16, 1/4 NPT, 3/8 NPT, 1/2 NPT, 5/8-11 UNC, and 3/4 NPT. Through tube options are also available for rod sizes ranging from 3/8" to 3/4". Any custom thread specification can be accommodated to fit your existing system.

These float balls serve a wide range of industries including food processing for monitoring oils and syrups, chemical manufacturing for tracking corrosive liquids, wastewater treatment for accurate level measurement in tanks, industrial process control including steam traps and vacuum systems, and sump pump operations requiring reliable liquid level activation control.

Yes, pressure testing is available for all magnetic float ball orders. Testing is performed to meet custom specifications defined by your application requirements. This ensures each unit is leak-free and reliable in high-pressure environments such as steam traps, vacuum tanks, and industrial liquid handling systems before it ships to your facility.
