Seco Seals,

Since 1969, SECO SEALS, Inc. has sealed millions of high-pressure flare tube fitting connections for aerospace, automotive, cleantech, geological, and marine applications. We are an ISO 9001: 2015 and AS9100D certified design and gasket manufacturer. Our goal is the elimination and prevention of leaks caused by the mechanical failure of connections between fittings for fluids and gases in any environment from the depths of the ocean to the far reaches of deep space. The Problem: Repetitive opening and closing of connections for liquids and gases provide a path for leaks on sealing surfaces. These repetitive actions may eventually require the replacement of the fittings which increase both labor and material costs. Benefits of Soft Annealing: Annealing is a heat treatment process that changes the physical and sometimes also the chemical properties of a material to increase ductility and reduce the hardness to make it more workable (malleable). Ductility is the ability of a solid material to stretch under tensile stress, i.e. when a metal is stretched into a wire. Annealing copper or any other metal involves heating it to a specific temperature and allowing it to cool at a specified rate. This process removes impurities in the grain, increases the metal’s ductility, and reduces its hardness ( softer, more malleable). Why Use Our Products: SECO SEALS’ flare gaskets allow the unlimited use of fittings by replacing the gasket after each use. The SECO flare gasket is used to protect the surface of the fitting and the flare tube. These soft annealed crush washers improve performance of the connection by custom forming into the slight imperfections of the fitting or flare surface finish.
