Oil-Resistant Buna-N Rubber Balls

- Color: Black
- Temperature Range: -40° to 212° F
- Tensile Strength: 1,800 psi
- For Use Outdoors: No
Use these balls as seals in pumps and check valves or let them bounce inside of vibrating sifters for an effective screen cleaner. Buna-N is also known as nitrile, NBR, and acrylonitrile butadiene. It offers good resistance to petroleum-based oils.

Chemical-Resistant Viton® Fluoroelastomer Rubber Balls

- Color: Black
- Temperature Range: 0° to 400° F
- Tensile Strength: 1,500 psi
- For Use Outdoors: Yes
Resistant to harsh chemicals and high temperatures, these balls stand up in applications as extreme as aerospace fuel systems. You can use them as seals in check valves and pumps or bounce them in vibrating sifters to clean screens. Made of Viton® fluoroelastomer rubber, also known as FKM, these rubber balls resist chemicals such as nitric acid, ethylene glycol, and isopropyl alcohol. Compared to Aflas, this rubber has better resistance to solvents and petroleum-based fuels. However, it doesn't hold up as well to steam and strong acids as Aflas.

Weather-Resistant EPDM Rubber Balls

- Color: Black
- Temperature Range: -40° to 225° F
- Tensile Strength: 1,500 psi
- For Use Outdoors: Yes
Made of EPDM, these rubber balls won’t degrade from sunlight, ozone, or water. They can be used to clean screens inside vibrating sifters, dampen vibration inside assemblies, and seal pumps and check valves.
