Flange Faces

As you start to consider purchasing flanges or gaskets, you’ll see a variety of terms used that you may not have come across before. Flange faces are the surface area that will receive the gasket, allowing them to come together to create a seal when put under...

Octagonal Ring Type Joints

A ring-type joint is a metallic ring that is machined to sit between two mating surfaces, where it will be compressed to provide a high-quality and reliable seal. Ring-type joints are vital components in various applications across multiple industry sectors,...

Blind Flange vs Blank Flange

Small pieces of mechanical equipment flanges continually play a vital role across numerous industries and applications. In essence, we use flanges to connect pipes to each other, with flanges also found in valves and specific application fittings too. Due to the...

Types of Flanges

Businesses in a variety of industries rely on flanges to join pipes or components together or to keep equipment secured to a surface. When it comes to choosing the best types of flange for your processes, you’ll want to take the time to research the different options...

Threaded Flange

Threaded flanges are probably the most recognisable of all flanges due to their screw thread design that is used to connect it to the pipe. Threaded flanges, also known as screwed flanges (for obvious reasons), require a male and female thread to create a connection...

Slip On Flange

A slip-on flange can also be known as a hubbed flange, which, as the name suggests, has a hub with a very low profile. Why is this important? Because this type of ring type joint gasket has an internal diameter larger than the connecting pipe, allowing you to slide it...

Weld Neck Flange

Also known as tapered hub flanges or high hub flanges, weld neck flanges are a specific type of gasket with a protruding ridge and long neck used to connect pipework and provide you with a high-quality seal. Weld neck flanges, in particular, are a popular choice when...

Nitrile vs Viton® – What is the Difference?

As you start to make a decision about what type of O-rings to purchase for your business, you might wonder what material is the most suitable for your unique needs. Every business operation has different requirements for their O-rings, such as the temperature,...

Aflas vs Viton

When it comes to choosing O ring suppliers in the UK, you’ll find that there are a wide range of materials on offer for you to choose from. Many people find that the options can seem quite overwhelming, with some materials having similar properties but offering...

EPDM Gasket

Both the automotive and construction industries have started to use EPDM gaskets more frequently in recent times. This rubber material is UV light resistant and has many fantastic properties that make this part highly effective for a wide range of processes. Keep...

Gaskets and seals for Aerospace

Gaskets and seals for AerospaceGaskets and seals used for aerospace applications and equipment must be of premium quality and to a substantially high standard. 

They are used across a range of applications such as radars, antennas, lighting, access panels, electrical conductivity, pressure sealing, and so much more. 

This makes choosing the right aerospace gasket essential.  

You need to ensure you have the right solution for the right application. Meeting all set criteria, as well as meeting several performance improvements compared to your average seal. 

What to look for in commercial aerospace gaskets and sealings 

A good rubber gasket all comes down to the type of material you use. 

You need a gasket material that can withstand various levels of electrical resistance. A gasket that is corrosion-resistant offers shielding effectiveness, fluid resistance, and can still perform under wide fluctuations in temperature. 

You need…. 

A gasket material is known as urethane-filled expanded aluminium. 

This impressive gasket material offers everything you could want from a seal and more. 

Its high surface affinity and the association with urethane binder systems help to create a sealing solution that fits perfectly within the fuselage and externally mounted aircraft devices. 

What does this mean to you? 

You can rest assured that you have the perfect seal and highest chemical resistance against all of the most commonly found aviation fluids. 

What is also essential in aerospace gaskets and seals is that they must be suitable to withstand and survive lightning strikes. 

This is why expanded aluminium is recommended to help improve electrical performance, eliminating electrical contact resistance. 

Ultimately, the expanded metal provides highly efficient electrical systems, optimizing grounding performance, and more. 

However, one of the most popular benefits of urethane-filled aluminium gaskets is that they help to reduce corrosion, providing a much longer lifespan. 

For this reason, aircraft manufacturers can expect less component replacement and rework most associated with corrosion. Saving on both time and money. 

What’s more, these gaskets are also easy to install. 

Often we may also talk about aluminium alloys; these are the materials that provide a clear benefit to airframes, associated stress fatigue, and cracking. These particular gaskets act as a conductive medium, almost acting like a sacrificial entity, promoting even distribution of surface load, reducing and indeed eliminating stress points and pitting occurrences. 

It may also be a requirement to opt for custom elasto proxy fabric gaskets, where this type of custom gasket is used in mass transit, military aerospace gasket and seals, medical, and aerospace applications. 

Urethane-filled seals ultimately perform much better than other seals in the market, for all aerospace style applications. 

This makes them the preferred aerospace application gasket due to their outstanding corrosion resistance, shielding efficiency (superior electrical conductivity is one of the main functions of shielding gaskets used in aerospace applications), fluid resistance, electrical resistance, as well as operating well under extensive temperature ranges. 

Designers, therefore, rely on the sealing performance of these gaskets. Performing when subjected to specific torque values for aerospace devices, as well as providing more chemical resistivity and sealing efficiency against aviation fluids. 

Due to urethane gaskets being resistant to corrosion, you can expect a reduction in aircraft TCO. Reducing water entry and the result of an electrolytic environment. 

Components and indeed, fixings such as seals and gaskets used in the aviation sector should adhere to several requirements.  

For example, these aviation devices require electromagnetic interference shielding materials that provide resistivity to unwanted radiation. 

At Specialist Sealing Products, we offer a wide range of seals and gaskets available, manufactured in various materials. Trust us when we say we’re confident to have a seal suitable for a wide range of applications, and specialist applications found in the aviation sector.
