Floating Roof Seals

TCI manufactures state-of the art PTFE/fiberglass composites and 100% PTFE floating roof seal materials to fabricate secondary wiper seals, single and double wiper seals, external floating roof seals, vapor barrier fabrics, and secondary seal solutions. Our products are designed to withstand the harsh environmental conditions of both internal and external floating roof tanks, especially in above ground storage tanks that contain petroleums. TCI’s materials do not allow gapping and offer superior vapor control and longevity, making them a safe, long-term option for your floating roof seal needs. They are excellent at preventing product loss and atmospheric contamination in above ground service tanks, where they can also serve as a weather shield.

Because elastomeric products are chemically susceptible and can be destroyed by corrosive additives in petroleum, the floating roof seal industry has advanced to using PTFE-based sealing materials made from inert PTFE plastic material. These chemically resistant floating roof seals have a longer life span and can eliminate concerns of chemical degradation. PTFE/fiberglass composites are compatible with petroleums, and 100% PTFE materials eliminate concerns of chemical attacks, regardless of chemical severity internal or external to the tank.
