Water- and Steam-Resistant EPDM O-Ring Cord Stock

In addition to water and steam, this EPDM cord stock resists diluted salt solutions, ethanol, and isopropyl alcohol. Use it to make round-profile O-rings, which are suitable for a wide range of static and dynamic sealing applications.

Make-Your-Own O-Ring Kits with Cord Stock

Everything you need to make custom O-rings on demand. These kits include cord stock, a razor blade, a splicing jig, and adhesive. The adhesive does not work well on silicone—if you want to make silicone O-rings, consider a hot-bonding kit instead.

Buna-N resists grease, hydraulic oil, and motor oil, in addition to mild chemicals and water.

Viton® fluoroelastomer holds up to a wide range of chemicals. It also resists transmission fluid.

EPDM withstands water, steam, and glycol-based fluids, including brake fluid.
