Since the beginning of time, mankind has gazed upwards to the stars dreaming of space flight and exploration into the celestial bodies above them. With advances in technology and contemporary approaches to space flight, mankind has pushed itself into the stars achieving the once deemed impossible. At the root of this achievement are the great leviathans of space travel. Giant rockets that rely on critical propulsion and liquid oxygen fuel tank systems delivering payloads into velocities achieving Low Earth Orbit.
These intricate and highly engineered systems rely on many components and assemblies to function properly. Valves, actuators, fuel tanks, and ground support systems are all critical to launch success and recovery. We keep those systems in the air and off the ground with high-performance cryogenic sealing systems for space exploration and aerospace applications.
Typical applications of our sealing solutions are the sealing of tank joints and doors. Our seals are used in applications involving liquid hydrogen and liquid oxygen. Our 100 series and 800 Series seals are typically utilized in cryogenic conditions where application requirements call for storage of these fluids in liquid states at high pressure.
Our seal designs utilized in fuel tank joints and doors can be designed to large diameters and non-standard groove sizes and shapes. We employ a robust Polycon Material library to ensure performance in risk-averse operating conditions.
Zero leakage requirements are required to prevent blowouts and potential catastrophic explosions. As such our seals are designed, manufactured, and delivered carefully to ensure performance-critical operating parameters.

Typical Applications in Rocket Engine propulsion systems include cryogenic valves, valve equipment, butterfly and anti-blow-out valves and POGO valves along fluid lines and joints, liquid hydrogen and liquid oxygen turbo-pumps and injectors, and ducts and manifolds.
Seals and sealing components designed for valves used in space applications are inherently unique. They operate in one of the most severe, mission-critical environments in the universe. Extreme variations in pressure and temperature characterize space exploration and science with cryogenic temperatures at the forefront.
