Advanced Sealing Technology


Advanced Sealing Technology (AST) was started in 1988 by a group of ex-Chesterton engineers, including the engineering manager at the time. They manufacture in the US, have same day delivery performance of 94%, have very competitive pricing that hasn’t increased since 1999. They have a product line that includes single and dual cartridge seals, OEM seals, and component seals. More detailed information can be found on our website at AST also offers rebuild kits for their mechanical seals. While many mechanical seal companies require you to ship the used seal to them for repair, they offer rebuild kits for mechanical seals which allow you to quickly and inexpensively rebuild them. Rebuilding the seal in house may save you significant time and cost (shipping and inventory costs).
