Protecting your seals

Dust gets everywhere.  We see it across the surfaces of our homes and even in our workplaces, especially when the light shines through to show it in its full glory!  However, dust that seeps and builds up within engineering equipment can be disastrous.  Causing damage...

Importance of durometer testing

Durometer or shore durometer is a way for industry professionals to measure how hard such things as plastic, rubber, and non-metallic materials genuinely are.  Its focus is to measure on a Shore A or Shore D scale, looking at how robust material is when examining its...

Metal Detectable O Rings

Metal detectable o rings became a necessary must when it was identified that some chemicals, exposure to extreme temperatures, and continuous vibrations could cause failings in standard o rings.  Failings that not only mean a breaking of the seal, but there is also an...

Tips for best o ring maintenance

If o rings are not maintained, leaks can occur, and water and other fluids can enter the appliance or application, and even product in the mix!  If this happens, damage can occur to internal parts and mechanisms, causing deployment failings, potential false readings,...

What you need to know about O Ring Lubricants

Silicone grease and lubricants aren’t just a nice to have for o rings, but they can quite often be a must-have.  However, with so many greases and lubricants to choose from, it can often be a minefield choosing the best ones and the right ones for your o ring and...

O Ring Replacement

Replacing an O Ring in pressure washer wands is probably one of the most common replacements you'll find when working with seals.  Unfortunately, O Rings don't last forever, and over time they do deteriorate, and you will require an O Ring replacement.  It's important...

Reasons behind seal failure and a look into seal replacement

Unfortunately, there are occasions where O-rings, in particular, fail.  The failure of these seals is not simply due to one factor, but various factors that can occur across a range of applications – hence why locating the exact cause of such problems is just that, a...

Gaskets and seals for Aerospace

Gaskets 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,...

Finding the best sealing materials for Food Grade Applications

You will find rubber seals across various industries, providing an important element and operating as a vital fixing across a wide range of different applications and equipment.  However, these FDA gaskets must follow strict, set guidelines, in terms of their material...

The Evolution of Gasket Solutions

When we talk about gaskets and the history of a gasket, we must start at the very beginning.  What is a gasket?  Ultimately, a gasket is a manufactured seal that is used to fill the gap/space between two or more surfaces.  Gaskets are typically manufactured by cutting...

Flange Gasket materials – What you need to know

Flange Gasket materialsGetting the most out of flange gasket materials and ensuring the performance of the gasket is not affected when you come to use it, means several things must be taken into consideration. 

For example, factors such as their design, how they’re manufactured, installed, the process conditions, and how they are stored all play a role and have an impact on the final product. 

Storage is the one factor, however, which is a lot lower down on the priority list than what it necessarily should be.  Unfortunately, what we tend to find is that we store gaskets for more extended periods than necessary and often in places which aren’t always ideal. 

In this post, we look at the best storage situations for flange gasket materials and spiral wound gaskets, to help preserve their performance and capabilities. 

Gasket Materials 

Gasket materials will fall into one of three categories.  These include: – 

  • Non-metallic gaskets
  • Semi-metallic gaskets
  • Metallic gaskets

Non-metallic gaskets can also be known as soft gaskets and are fabricated from rubber, fibre, PTFE, and graphite.  

Metallic gaskets are manufactured from one or a combination of different metals. 

Leaving semi-metallic gaskets to be made up of both metal and non-metallic materials. 

Spiral wound gaskets are the most commonly found and used semi-metallic gasket; where the metal provides the strength and the non-metallic elements provide the sealability and conformability. 

Making sure these gaskets are stored correctly and in the right environment is critical to ensuring their overall end performance. 

Impact of the environment on materials 

Gasket materials which include elastomeric binders will inevitably deteriorate over time.  This is because the fibre materials themselves are made up of complex materials. 

The materials used in these types of gaskets are often susceptible to deterioration from extreme ambient temperatures, which can often mean that degradation can also occur when they are exposed to direct sunlight. 

Ultimately, it is often the filler components within gaskets that cause the most significant deterioration to the gasket itself.  Of course, this does all depend on the composition of the material used, as well as its quality and how it is stored. (A professional gasket manufacturer will be able to provide you with the right filler materials for your gasket and all to suit your requirements). 

The good news is, there are gasket materials which are entirely unaffected by storage periods.  

PTFE and graphite are two such materials that contain no binders and virtually have an indefinite shelf-life. 

However, be aware that for metallic and semi-metallic gaskets that use such materials, excessive dust can cause issues when it comes to compatibility, while exposure to moisture and humidity can cause oxidation of the metal components. 

Check out our blog post on OPTIMUM STORAGE CONDITIONS FOR GASKETS to find out how to prevent a reduction in quality in your gaskets. 

As flange gaskets are used to create a static seal between two flange faces, they must perform to a high standard.   Working in varying conditions, with fluctuations in temperature and pressure, these seals are used to keep liquids and gases in place. 

Making sure they’re stored correctly and understanding how storage can affect shelf-life helps maintain materials for longer and avoid complications such as installation difficulties and damage to the overall seal. 

At Specialist Sealing Products, we can provide a range of gaskets suitable for a multitude of purposes.  We can also give more information on the optimal storage conditions as well as update you on shelf-life for gaskets and the materials used within the gaskets we currently stock.
