Spiral Wound


Spiral wound, also known as graphite rope, is a true multi-service material that provides outstanding performance in a wide variety of demanding applications. Manufactured from high-purity flexible graphite, it is formed into a yarn then braided into its final form without wire reinforcement or binders.

The pressure sealing capabilities and good recovery performance of spiral wound metallic gaskets provide long-term performance for harsh, high-temperature environments where effective sealing is vital.

Precision engineered products from Denver Rubber Company are ideal for flanged joints, heat exchangers, boiler handholes, manholes and high-temperature applications and other demanding applications.
