Custom Vulcanized O-Rings

For applications requiring a non-standard diameter o-ring a custom vulcanized o-ring is often the fastest and most cost effective solution. COR’s custom vulcanized rings are produced from extruded o-ring cord, cut to length and hot spliced using heated dies and a heat sensitive bonding agent. The heated die provides consistent heat and helps form a clean and visually appealing finish to the joint. Most of our elastomers can be vulcanized. Are Vulcanized O-Rings right for your application?
