Stainless Steel Hollow Balls

Round float balls are available in diameters ranging from 1-1/2" to 14", including 2", 3", 3-1/2", 4", 5", 6", 7", 8", 10", and 12". Oblong floats come in sizes such as 2x6", 3x5", 3x6", 3-1/2x12", 7x12", 7x16", and 9x14". Custom sizes are also available upon request.

Yes. We can tap any thread specification into our float balls. Common thread options 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 configurations are also available to fit 3/8", 1/2", 5/8", and 3/4" rods. Custom fittings can be designed to integrate directly with your existing system.

Yes. Our stainless steel hollow balls are widely used in food processing for liquid level monitoring in tanks and vats containing oils, syrups, and other liquids. Constructed from 304 or 316 stainless steel with a polished or brushed finish, they meet the hygiene and durability demands of food-grade environments and resist corrosion from food-based liquids.

Three finish options are available: matte (unfinished with a visible weld ring), brushed (a smoothly polished weld seam), and fully polished (a mirror finish). The choice of finish affects both aesthetics and hygiene suitability. Polished finishes are recommended for food processing and decorative applications, while matte finishes are common in general industrial use.

Yes. We offer custom magnet integration where magnets are sourced and assembled inside the float balls. This enables precise liquid level detection in systems that rely on magnetic switches or sensors. Float balls with magnets are commonly used in float valves, vacuum tanks, sump pumps, and complex industrial level-detection systems requiring reliable magnetic activation.

Yes. We have equipment to pressure test all float balls to meet your custom specifications before they ship. Pressure testing ensures the integrity and reliability of each float ball in high-pressure environments such as steam traps, chemical processing systems, and vacuum tanks. Testing parameters can be adjusted to match your exact application requirements.
