Aero Seals Description
"Aero seals" can refer to various types of seals used in the aerospace industry.
Sealing types used in aerospace applications:
Static seals are used to form a barrier between fixed parts to prevent leakage of liquids or gases. Commonly used in aircraft engines, hydraulic systems, fuel systems, and other critical applications.
Dynamic seals are used in applications where there is relative motion between components. Typically used in aircraft landing gear, drive systems, and engine components. These seals are designed to maintain sealing integrity while accommodating motion, such as reciprocating or rotational motion.

O-rings are one of the most commonly used seals in aerospace applications. These circular cross-section seals are made of elastomeric materials and are used to create reliable leak-proof seals in a variety of aircraft systems, including fuel, hydraulic, and pneumatic systems.
Gaskets are flat or shaped seals used to create a seal between two surfaces. They are commonly used in aerospace applications to provide static sealing between components such as engine casings, access panels, and aircraft structures.
Rotary shaft seals, also known as oil seals, are used to prevent fluid leakage along a rotating shaft. These seals are commonly used in aircraft engines, transmissions, and other rotating parts.
It is important to note that the selection and application of seals in aerospace systems requires careful consideration of factors such as temperature, pressure, compatibility with fluids, and compliance with industry regulations and standards.
Certifications
Aero seals manufacturers must meet strict quality and performance requirements and may be required to obtain relevant certifications (such as AS9100, NORSOK, ASTM D2000, MIL-SPEC) to ensure the airworthiness and safety of aerospace components.
