Vulcanized O-Rings

If you have a large, non-standard, small quantity or need an o-ring fast, a vulcanized o-ring might be the perfect solution.

When can I use a vulcanized o-ring?

A vulcanized o-ring is a good fit for applications with no movement of the seal or sealing of the hardware by the o-ring, for example, static applications. Likewise, they are an excellent choice for filtration, large valves, and pharmaceutical applications. To clarify, anywhere a flange needs a seal. In short, we can use a wide range of elastomers to vulcanize o-rings in virtually any size or shape.

Contact us today to see if a custom-engineered vulcanized seal fits your need.

How are vulcanized o-rings made?

First, we cut a continuous-length cord to length. Next, we apply a bonding agent to the ends and then join them together in a mold at a high temperature for a set time. Finally, this process forms the molecular bond necessary to create a strong joint.

Additionally, the bonding agent consists of the uncured compound and adhesive. For example, if your compound is Viton™, it would be uncured Viton™ and adhesive.
