Sealing Products for the Military and Aerospace Industry

The Military and Aerospace industries operate in some of the most challenging environments on Earth—and beyond. As machinery takes to the seas, skies, and outer space, the integrity and performance of every component, especially the sealing solutions, become paramount. At Global O-Ring and Seal, we pride ourselves on profoundly understanding these industries’ unique requirements.

Military Specifications (Mil-Spec) o-rings withstand the rigors of military applications. Meeting and often exceeding AMS, AS, AN, M, MS, MIL, and NAS standards, these seals are built for durability, addressing the challenge of long-term performance under harsh conditions. Their applications range across all Military and Aerospace equipment areas.

Additionally, the AS9100D standard represents the pinnacle of quality management systems specifically designed for the aerospace industry, incorporating the rigorous demands of aviation, space, and defense sectors. It builds upon the foundation of ISO 9001 standards by introducing aerospace-specific requirements to ensure the safe development, production, and distribution of high-quality aerospace parts and products. By securing AS9100D certification, organizations affirm their ability to meet these stringent requirements, facilitating stronger relationships within the aerospace supply chain and enhancing overall performance and reliability.

Critical Challenges of the Industries

  1. Extreme Temperatures: Military and aerospace equipment often has to operate under extreme conditions, from the deep cold of outer space to the high heat of jet engines. Ensuring that every component, especially the seals, can withstand these temperatures is crucial.
  2. Corrosive Environments: Military and aerospace machinery frequently come into contact with corrosive substances, such as fuels, oils, and other aerospace chemicals. The longevity and performance of these machines depend heavily on the ability of their components to resist such corrosive environments.
  3. High Pressure: The pressure conditions that military and aerospace equipment must endure, whether deep underwater or at high altitudes, present a unique challenge. Seals used in these industries must maintain their integrity under such extreme pressures.
  4. Durability & Longevity: The long service lives expected of aerospace and military equipment mean that every component must be durable enough to withstand prolonged use in harsh conditions, including resistance to wear and tear, aging, and environmental degradation.

Addressing these challenges requires a deep understanding of the industry’s nuances and specific requirements and a commitment to providing high-quality, reliable solutions. At Global O-Ring and Seal, we’re dedicated to meeting these challenges head-on, supplying a diverse range of sealing solutions that are up to the task.
