"In 1989 I was an oil refinery firefighter.
At refineries, sandbagging is the customary procedure to temporarily seal potentially explosive process sewer drains during hotwork. But sandbagging can be a messy, drain-fouling, labor-intensive technique. Some friends and I talked of a better way. Eventually we came up with our Orignial NsertAseal Inserts and that was the beginning of NsertAseal. We Incorporated in 1991. Since then, our line of vapor emissions control and fire safety products has expanded significantly."   --Jim Webb

We still sell Original Inserts, but our primary focus now involves retrofitting sewer systems with water seals that are semi-permanently caulked or grouted into place. These seals allow waste fluid to pass through drains into the sewer system normally, but stop fugitive emissions from leaching back out into the atmosphere.

Our drain seals help the petrochemical industry comply with regulatory mandates and contribute to a safe, odor-free work environment. Our best-selling seals are our Vertical Pipe Trap (VPT) inserts for standard drain openings. We also produce large custom seals for junction boxes and catch basins. We also custom cast VPT's to solve unique drain problems on a case-by-case basis.
