Product Description

These Nitrile Rubber balls are molded from a 70 Shore A nitrile compound specially formulated for grinding. These balls are recommended for most typical pneumatic, hydraulic, or water applications. High speed centerless grinding combined with automatic gauging assures consistent part quality with close tolerances on both spherical and diametric dimensions. The resulting uniform finish ensures consistent sealing performance regardless of how the ball seats.

Still have no idea what I'm going to do with these but they were about the right size for adding to some waterlines as air-bleeds. They do make decent marbles...

These are perfect for making paracord monkey fists. These are lighter than using steel, and better for decorative key chains.

Just what I needed for my work. What more can you say about little rubber balls. They're balls, if you need black rubber balls these are the ones to buy!

I needed some rubber balls to make a check valve and these worked just fine.
They are round and rubber. That's what I needed and that's what I got.

These balls fulfilled the purpose that we purchased them for admirably. We use them as seals in CO2 release/refill canisters, and we are amazed at the results we are getting. Good product.
