O-rings suitable for the pharmaceutical industry

O rings are widely used across various industries to support a variety of different pieces of equipment and applications.  They provide an essential function and are ultimately moulded and manufactured to ensure they provide a continually high level of quality through...

The Best Chemical Resistant Gaskets for Sulfuric Acid

If you are using sulfuric acid on a regular basis within your industry, you might be aware of how corrosive it can be. While it can be useful for dyes, explosives, fertilisers, and many more applications, finding a chemical resistant gasket can often be one of the...

Different elastomers for o rings and various applications

An elastomer is a primary raw material used for most o rings. They are typically manufactured as gum rubber or manufactured synthetically, and surprisingly today, there are approximately over 32 different synthetic rubbers now available.  Elastomer compounds will...

Spiral wound gasket thickness – what’s best?

It is often recommended that using a thinner gasket type/material will result in better sealing performance.  Why?  Because thinner gaskets tend to require much less gasket stress to provide applications with the perfect seal, they also have an excellent response to...

Choosing the correct oil seal application

Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.  Of course, all rubber materials and seals will provide a range...

Nitrile rubber, NBR, and Buna-N – how well do you know your o ring materials?

A widely used elastomer, Nitrile, Buna-N, or NBR rubber, are all oil and fuel resistant and provide a great level of strength, making them a popular material for seals across various industries.  Suitable for a range of applications, this versatile rubber material,...

Optimum squeezing force for an o ring

It is true that the more squeeze you place on an o ring, the tighter the seal it will provide. In essence, the more squeeze (compression) you apply, the greater the force between the o ring and its mating hardware.  And ensuring you have the perfect seal is all...

O Ring Squeeze

The squeeze and shrinkage on an o ring are vital to understanding as these factors stand in the way of your application either experiencing a perfect seal or your application suffering from leaks.  You can measure the shrinkage of an o ring during...

Keeping your o rings bonded

EMI o rings. Those seal ring gaskets are made of silicone compounds, combining environmental sealing with electromagnetic interference protection.  Consisting of metal or metal-coated particles, silicone o rings are filled with silver, silver aluminium, or nickel...

The importance of mechanical seals when reducing water consumption in mining

Environmental considerations are at the top of most industry's agendas in the 21st century as companies evaluate and improve operations, processes, and systems.  Conserving water in mining is one such area that is now being investigated further with the rotation of...

Difference Between Gasket and Seal

Difference between Gaskets and SealsIf you want to make a selection out of gasket and seal for your project, then you might be thinking that they are almost the same products. In few ways, they might be the same as they perform similar functionality. However, there are some key differences between gasket and seal that you must understand before deciding which item is perfect for your project. Here is a detailed guide to the differences between gasket and seal that will make your decision easy:

A gasket is a piece that is placed between two parts to create a perfect joint between two surfaces. Gaskets are noted to fill irregularities and they are manufactured from sheet materials such as fibreglass, neoprene, felt, cork, silicone, rubber, paper, metal, plastic polymer etc.

A seal is a category and a gasket is one of the important types of seal. Apart from the gasket, you can find several others forms of seal such as shaft seals, mechanical seals, valve stem seals, liquid sealants, O-ring seals, rotary seals and many more.

The process of manufacturing seal involves a lot of machining and a specific size seal material. It is referred to as an engineered product and designed under special conditions. Seals are also known for showing characteristics that gaskets are failing to offer. This is the reason why a seal can provide better functionalities when compared it with gasket products.

A gasket is referred to as a static piece that can be used to close the leakage between two parts that are static and doesn’t show any relative motion. On the other hand, a seal is a dynamic piece that is used to avoid leakage between two parts that show sliding or relative motion. Another essential function of a seal cover gasket is that it doesn’t allow foreign particles like dirt or dust to enter into the joint.

In case the gasket breaks down, you need to replace the existing gasket with the new one. However, when the seal breaks down, you need to replace both seals and the bearing with the new ones. This is an application where a gasket can be quite handy when compared to a seal.

Both gasket and seal are used to avoid the movement of fluid from one direction to another because of the compressive forces. However, a gasket is a non-moving object and once it is placed in a particular position, it can’t be moved. On the other hand, oil seals can move very quickly from one location to another.

One more fundamental difference between gasket and seal is that gasket is usually made from hard plastic or asbestos material. On the other hand, seals (especially oil seals) are manufactured from the material such as synthetic rubbers.

This is a detail explanation of the difference between gasket and seal. It will definitely provide you with a helpful insight into how the mechanism of both these products works. Understanding subtle differences between both these items are essential for the successful execution of any project. Once you get to know the typical characteristics and unique functionalities of gasket and seal, you can definitely make a right choice of components for your project.
