Use these polyurethane balls as seals in pumps and check valves or let them bounce inside of vibrating sifters for an effective screen cleaner. They are made of polyurethane, which combines the shock absorbing qualities of rubber with the strength of plastic.

Balls with a steel core are heavier than standard balls, so they’re often used to offset buoyancy or to reach a specific weight.

Safely use these balls in food and pharmaceutical environments to clean screens in vibrating sifters or to act as a seal in pumps and check valves. They’re made with metal and chemical additives to set off metal detectors or X-ray machines if they fall into food, helping you comply with Hazard Analysis and Critical Control Point (HACCP) programs. The metal additive also ensures these balls will be caught by magnetic traps. These balls are FDA compliant for direct contact with food, and contain no BPA or plasticizers that could cause contamination. They’re made of polyurethane, which combines rubber’s shock-absorbing properties with the strength of plastic. To withstand rough use over time, these balls are designed to be abrasion resistant.
