Seco Seals, Inc. is a family-owned American manufacturer based in Costa Mesa, California, specializing in high-pressure tube fitting gaskets and conical seals since 1969. The company is a recognized leader in aerospace sealing technology, holding ISO 9001:2015 and AS9100D certifications. They serve a prestigious global clientele, including NASA, Boeing, Lockheed Martin, and Caterpillar, providing mission-critical components for extreme pressure and temperature environments.
Their core product portfolio features the SECO7 (37-degree flare gaskets), SECO45 (45-degree flare gaskets), and SECO11 (24-degree flareless gaskets), alongside specialized SECO77 kits and XYLAN-coated seals. These products are engineered from soft annealed metal foils—such as aluminum, nickel, stainless steel, and copper—to prevent leaks in fluid and gas connections by custom-forming to surface imperfections. Their solutions are designed to withstand vibration, full vacuum, and pressures exceeding 10,000 PSI, making them essential for rocket engines, spacecraft, hydrogen fuel cells, and deep-sea diving equipment.
Beyond aerospace, Seco Seals provides high-performance sealing solutions for the HVAC, automotive, marine, and petroleum industries. They offer extensive build-to-print and custom manufacturing capabilities to meet specific engineering requirements. With a commitment to 100% inspection and reliability, the company supports diverse applications ranging from commercial refrigeration and race cars to critical oxygen breathing systems and clean technology emissions reduction.
