Why Seals are Essential in Aircrafts?

When you’re cruising at 35,000 feet, it’s important to know that you can rely on the many seals throughout the aircraft you’re on. Whether they’re on the exterior flaps or the cockpit fastener windshield, a failed seal can have a huge impact on an aircraft’s performance. Aircraft Seals have to be up to snuff to deal with harsh conditions like extreme weather, high air pressure and dramatic swings in temperature. Some seals are even exposed directly to fuel and chemicals during manufacturing or operation.

Certain aviation seals with the highest demands require special engineering to meet the required performance levels. Because of this, significant research and development goes into the production of seals from composite materials. The introduction of composite seals has redefined what a seals’ function can be. They can be produced from a wide array of materials such as silicone, stainless steel, aluminum, or plastic depending on specific needs. Composite compounds have been especially useful for application on the exterior of aircraft in parts like flaps, rudders, and door seals, all of which have high demands and need seals designed specifically for that purpose. For example, wing seals need to be impervious to corrosion, so special materials are added to the composite to protect the seal.

Another way to specialize aircraft seals for certain tasks is to reinforce them with other materials. For instance, some seals need to be resistant to a massive range of temperatures from -40 F to 1,000 F. For this type of seal, a mix of silicone, fabric, and metal, reinforced with aluminum is used. Other seals have to be resistant to smoke, which can be done by reinforcement with materials specifically designed to be flame resistant.

With varying but equally-important requirements, aircraft connector seals are not a one-size-fits-all part. A seal tailored to your specific needs will last longer and operate without a hitch.
