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...

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...

How to preserve your gasket

Gaskets and seals don’t last forever. However, they are designed, or they should be, last for a considerable period.  In this sense, it is vital to look at ways to preserve your gaskets in order to avoid any application downtime.  Downtime that involves additional...

Important Design Features of Rubber Sealings

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 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 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 as an engineered product and designed under special conditions. Seals are also known for showing characteristics which gaskets are failing to offer. This is the reason why seal can provide better functionalities when compared it with the gasket products.

A gasket is referred as a static piece which can be used to close the leakage between two parts which 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 which show sliding or relative motion. Another essential functionality of seal over 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 seal breaks down, you need to replace both seals and bearing with the new ones. This is an application where gasket can be quite handy when compared to seal.

Both gasket and seal are used to avoid movement of fluid from one direction to other 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 other.

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.
