Reduce evaporation loss, minimize rainwater contamination of stored product and extend the life of primary seals by installing the Flex-A-Seal™ secondary compression plate seal.

The Flex-A-Seal™ patented design reduces product contamination due to weather conditions such as rain, snow and blowing sand with up to 98% shedding control capacity.

Flex-A-Seal™ is custom engineered, built for each tank and designed to maintain a minimum force against the tank shell of 20 lbs. per foot.

High vapor containment efficiency results in a payback period of 18 months.
