At Sealing Devices, we understand the boundless challenges and rigorous demands of the satellite and space industry. Special considerations must be taken when choosing sealing materials for space applications such as satellites, rockets, space vehicles, that may be subjected to harsh conditions, vacuum environments, and low NASA outgassing. Our mission is to provide the most advanced sealing solutions that meet the unique requirements of space exploration and satellite technology.

We have experience working with top satellite, aerospace, military and defense companies to customize solutions for their unique applications.  Trust Sealing Devices with supporting your next project.  We are a small, veteran owned, ITAR registered and AS9100 certified facility.

We have relationships with the top suppliers in the industry to fabricate and distribute what you need, on time and with extreme quality.  Some of our partners include: Parker, Chomerics, Rogers, Gore, 3M and more.

GORE® Protective Vents can prevent damage to the enclosure:

• They rapidly equalize pressures within the enclosure, in response to pressure changes (due to changes in altitude or temperature — as with a sudden heavy rain). This reduces stress on housing components and reduces the risk of premature seal failure, or cracks in the housing itself.
• They release gases that form when electronics within the enclosure heat up. This prevents the gases from reaching dangerous concentrations.

GORE® Protective Vents can prevent damage to the sensitive electronics within the enclosure:

• They prevent contaminants like dust, dirt and liquids, fluids or oils from entering the enclosure.
• They reduce condensation build-up, and the potential for corrosion, by allowing water vapor to pass out of the enclosure.
• They release gases to the environment, protecting electronic components from gas contamination.

Spring-energized seals provide reliability in hydraulic and pneumatic systems, as well as unpressurized dynamic systems.  These highly engineered seals are similar to hydraulic U-cup seals, but with a spring between the sealing lips to maintain constant contact with the sealing surfaces even without fluid pressure. These seals are available in a variety of materials and profiles to customize performance.

PTFE spring-energized seals are ideal for rotary applications where low friction is needed for normal operation. The PTFE can be modified with several different filler materials to tailor the seal characteristics to your needs. Sealing Devices offers Parker FlexiSeals, as well as similar alternatives.

Rogers BISCO® Silicones product lines are the world’s leaders in silicone foams used for gasketing and sealing applications. BISCO offers a wide range of cellular, solid and specialty materials that are produced in roll stock. These high performance materials are ready to be fabricated into gaskets, heat shields, fire stops, seals, cushions and insulation.

Benefits

• Resistant to temperature extremes, UV and ozone
• Extremely resilient to mechanical fatigue
• Excellent compression-set and creep resistance
• Compliance with the most stringent UL flame ratings
• Manufactured in an AS-9100 ISO-9001:2015 certified facility

Parker Chomerics electrically conductive elastomer gaskets are the superior choice for corrosion resistance, environmental sealing, and cost-effective EMI shielding.

These elastomers are available as:

• Extruded cord stock that can be sold as cut lengths or bonded to form a continuous seal
• Molded sheets that can be die-cut for greater part complexity
• Finished molded parts that offer 3-dimensional geometry and tightly controlled tolerances

Parker Chomerics SOFT-SHIELD® 4800 is a true multi-planar, Z-axis electrically conductive foam for indoor applications. It is based on the unique integration of electrically conductive silver-plated fibers into a low-density urethane foam, providing for a performance-driven, cost-effective EMI shielding solution. SOFT-SHIELD foam is also available in strip form with a number of cross-sectional shapes and sizes.

Gap fillers, a class of thermal interface materials (TIMs), are specifically designed to protect equipment and devices from the increasingly high levels of heat generated by chips and other electronic components.

These soft, highly conformable materials fill gaps of all sizes to improve heat conduction between heat-generating and heat-dissipating surfaces.

Special considerations must be taken when choosing EMI shielding and thermal interface materials for space applications such as satellites, rockets, telescopes, and other space vehicles that may be subjected to harsh environmental and regulatory requirements.
