Cord stock is O-Ring material, ready to be cut to create custom size O-Rings. There is a large selection of cross-sections available, and can be cut to any length you need or in standard put up lengths. We supply O-Ring Cord stock either as Pre-Cut lengths, custom cut length or Vulcanized into custom O-Rings. Available in either metric or standard sizes, unless otherwise specified all our O-ring cord is manufactured in the U.S. to BS ISO 3302-1, Class E2 as standard. We also Vulcanize O-rings in many sizes and compounds in house, if you know the O-ring size needed.
