SECO SEALS, an aerospace manufacturer of high-pressure tube fitting gaskets, is ISO 9001:2015 and AS9100D certified. We are a family-owned American small manufacturer in business since 1969. Our industry standard product line, SECO7 “37 Degree Flared Tube Fitting Conical Seals,” is renowned in the industry for its ability to prevent leaks in any environment. Our goal is to eliminate and prevent leaks caused by the failure of fittings in fluid and gas connections.
These flare gaskets are designed to withstand vibration, temperature changes, full vacuum, and exceed the pressure ratings of fittings. This allows the fittings to be used repeatedly by replacing the gasket after each use, improving performance and avoiding the need to replace fittings.
The ISO and AS quality certifications guarantee the highest quality and reliability, backed by our commitment to excellent customer service. We also offer build-to-print sealing solutions for extreme pressure and temperature applications made of the highest quality metal foils.
SECO SEALS CAGE (Commercial and Government Entity) Code is 33447, and the ECCN (Export Control Classification Number) is 9A991.d.
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.
Why Use Our Products
SECO SEALS’ flare gaskets are designed for deep space to never fail and never wear out. You put it in behind the wall and it will be there 100 years later. It is designed to expand and contract with the systems. It withstands vibration, temperature changes and full vacuum. Additionally, it exceeds the pressure ratings on your fittings. The SECO7, 37-degree Conical Seal, goes up to 10,000 PSI. Its newer cousin, the SECO45, 45-degree Conical Seal, is usually rated at 500 PSI.
Using our flare gaskets turns the weakest link of your system into your strongest link. These 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.
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.
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 increases the metal’s ductility, and reduces its hardness (softer, more malleable).
