In the Beginning

Flexaseal Engineered Seals and Systems, LLC began in 1983 primarily as a welded metal bellows seal manufacturer dealing with a limited distributor base in the United States. Now four decades later, Flexaseal has expanded to four physical locations with sales agents and distributors worldwide. Our current facilities include:

  • Our Headquarters in Williston, Vermont with approximately 66,000 square feet and 120+ employees
  • Our Seal Repair and Service location in Gonzales, Louisiana with an over 5,000 square foot state-of-the-art facility
  • Our Seal Support Systems and Service facility in Houston, TX
  • And since 1996, Flexaseal Brazil in Sao Paulo, Brazil with approximately 12,000 square feet and 55 employees

Our seal and seal support system options have expanded as well. In addition to our core line of edge welded metal bellows and the world’s first fully split cartridge mechanical seal, our products include single and dual cartidges, engineered cartridges for dry-running operation and heavy duty slurry applications, and industry-specific sealing solutions for cryogenic and hermetic equipment.

The Flexaseal Advantage

Our core commitment at Flexaseal Engineered Seals and Systems, LLC is to be at the forefront of industry’s technical advances. Our facilities contain state of the art bellows welding capabilities, CNC machining centers, quality control standards, and extensive inventory systems. We also offer seal repair capabilities to refurbish not only our seals, but our competitors’ as well. In addition, we are successfully partnered with many distributors and agents both domestic and international, enabling us to furnish on-site consultations and assistance.

Our mission is to supply our customers and end users with products of the highest quality. We believe essential elements to this process are courteous and prompt quotations and customer service, quick and dependable deliveries, product training, informative literature and in-plant surveys, and skilled engineering support.
