Rubber Balls
 |
Use rubber balls for a variety of applications, including cleaning, vibration damping, and sealing.
Tear- and Abrasion-Resistant Polyurethane Rubber—These balls combine the shock-absorbing qualities of rubber with the strength of plastic. Use as seals in pumps and check valves or let them bounce inside of vibrating sifters for an effective screen cleaner.

Floats for Threaded Rods
Polypropylene Cylinder Floats
 |
Polypropylene floats are lightweight and meet NSF/ANSI 61 standards for safe use with drinking water.
Cylindrical floats are all self-tapping except those with a 4” diameter, which have a threaded hose connection.
304 Stainless Steel Ball Floats
 |
Stainless steel floats have excellent corrosion resistance and are also for use with oil.

Shock-Absorbing Flange-Mount Ball Transfers
 |
A thick rubber mounting cushion underneath these ball transfers absorbs impact and reduces vibration.
Weight capacity is given for the ball up orientation. Using these ball transfers in a ball down or angled orientation could reduce the weight capacity stated.
Stainless Steel Ball—Stainless steel balls offer the most corrosion resistance. They also don’t need to be lubricated.
Nylon Ball—Nylon balls are nonmarking.
