We offer sealing solutions to industry professionals that require exceptional standards for their industrial seal rings.

O-rings, or industrial seal rings, are manufactured with care and consideration for their purpose. Primarily composed of elastomer, O-rings are the trusted seal of millions of applications worldwide. As such, their quality must be infallible during their compression between parts. A break or split in an industrial seal ring can be catastrophic, so your manufacturer must stand behind their products without question. Our clients know they can count on our customer service and manufacturing capabilities to provide them with reliable parts.

Nitrile Seal Rings

A critical component in oil and gas lines is that the seal for your application is absolute. Leaks cannot happen because they compromise the integrity of the line. When that happens, the domino effect of production loss, clean-up, and repair can be financially prohibitive. Prevent the problem from happening by using nitrile seal rings to increase the probability of a secure connection. Manufactured using oil resistant synthetic rubber, our nitrile rings are a resilient product that supports the integrity of your lines. This reliability provides you with a secure knowledge of leak-free performance.

Make the right choice when it comes to your lines; our nitrile seal rings are manufactured with your business in mind. We understand the critical nature of an effective seal in your industry. Our variety of nitrile seal ring sizes offer multiple options for applications, and we can discuss the most appropriate rings for your requirements. Talk to one of our experienced staff about your industry regulations and product parameters, and we can suggest what you need to get the job done right. Don’t take the chance of losing production time with leaks or line breaks; give us a call about our nitrile seal rings.
