Bringing process drain systems into compliance with clean air requirements, making them safe from fire, and stopping odors can be a problem for oil refineries. NsertAseal Corporation has quick and cost-effective solutions. Our products are reliable. They do the job well. Installing our inserts is more economical than other sewer-sealing techniques, both when retrofitting existing systems, and in new-construction applications.

Our patented 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, and custom cast VPT's to solve unique sewer drain problems on a case-by-case basis.

Our VPT's, Box Traps, and custom-fabricated seals provide a barrier against the emission of noxious, pungent, and worrisome odors from refinery sewer systems. Use of our ruggedly constructed and economical products demonstrates an oil refinery's desire to maintain a good relationship with employees and neighbors.
