Abrasion-Resistant Polyurethane Rubber Balls
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.
