aSURE's patent-pending design design marries the properties of an elastomaric gasket in to a singular sanitary rigid sanitary Tri-Clamp fitting.


TBL’s proprietary manufacturing method employs no adhesives and no clips to hold the gasket in place. There are many important features that set the aSURE apart from traditional methods that utilize a stand-alone gasket and fitting.

TBL Plastics offers sanitary tri-clamps and gasket fittings with a unique design that prevents contamination and meets even the most stringent hygienic practices. Traditional sanitary fittings typically consist of the following three components:

  • Two ferrules
  • Gasket
  • Clamp

Most ferrules are made from stainless steel and must conform to Bio Processing Equipment standards to ensure that they will work with each other, regardless of the manufacturer. The gasket seals the ferrules from leaks when clamped. The clamp compresses the gasket between the two ferrules, effectively leak-proofing the ferrules. With aSURE fittings, the built-in gasket becomes part of the sanitary tri-clamp fitting. The fitting and gasket are combined in a single product, manufactured without adhesives and/or clips holding the gasket in place. This adds another layer of safety and security to sanitary fittings.

The aSURE fittings product advantage:

  • Cost Effective Without fear of contamination, there is less product waste and scrapped batches due to accidental contamination
  • Easy Installation Most tri-clamps on the market require two men to safely install without contamination. aSure fittings ensure the built-in gasket remains sterile by requiring zero contact between the user and the gasket
  • Product Safety The self-adjusting lightweight, limited slip design allows for a greater seal with no risk of misalignment
