Make Seco Seals your choice for gasket applications.
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 marine technology, geological services, automotive (race cars) to aerospace, Seco Seals has developed solutions that became the industry standard.
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.
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.
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).
New Product Line – SECO45 Flare Gaskets
Since 1969, Seco Seals has sealed millions of high-pressure 37 degree flare tube fitting connections for aerospace, automotive and marine applications. Now this simple world class technology is available for 45 degree flare tube fitting connections.
Seco Seals is introducing its newest product line, SECO45, 45 degree flare gaskets. The SECO45 copper flare gasket is available in seven sizes. The gasket is intended to never fail and never wear out. Additional optional “tin” or “silver” plating for SECO45, 45 degree flare gaskets, will be coming soon.
Service and warranty providers for HVAC, hydraulic, pneumatic, automotive, and other applications utilizing 45 degree flare fittings need a reliable solution that eliminates repeat warranty or service calls for the exact same problem. Typical applications utilizing 45 degree flare fittings are LP and Natural Gas, flammable liquids, instrumentation, refrigeration, power steering, HVAC, hydraulic and pneumatic systems.
Seco Seals – the 100% Solution
In our effort to remain on the leading edge of our industry, Seco Seals has expanded its capabilities for “build to print” sealing solutions for extreme pressure and temperature applications made of the highest quality metal foils between 0.005″ and 0.015″.
