Responding to the industries needs we researched and developed a tough and highly durable internal floating roof tank secondary seal called Waffle Seal.
Our Waffle Seal is the simplest wiper seal system, and the most economical solution for minimizing product loss through evaporation.
By integrating cutting-edge technology with resilient polyurethane compounds, the Waffle Seal delivers top-tier performance as a secondary wiper seal, making it the ideal choice for durable urethane wiper seals for storage tanks
Maximum sealing reliability wasn’t an accident, it was one of the objectives when designing the Waffle Seal. Our engineers understood that the overall design must be kept simple for practical, easy installation, product economy, and minimal maintenance.
The solution was a combination of modern manufacturing techniques with the highly flexible and resilient properties of polyurethane. The resulting product, a durable urethane wiper seals for storage tanks we named Waffle Seal, met our criteria to the letter.
Typical internal tank Waffle Seal application.
Twenty-five and fifty-foot segments of our seal can be easily bolted onto existing or new floating roofs without distortion or puckering. Section joints are bonded together with a special adhesive available in our splice kit.
Small Tanks? No Problem!
Order your seal pre-radiused per your tank’s diameter.
Installation is the same, whether the oil storage tank is either an open or enclosed type. This tough, durable seal acts as a secondary seal in an open tank and as the primary seal in an enclosed tank.
