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...

Things to Consider in Selecting the Right O-Ring for Your Needs

Things to Consider in Selecting the Right O-Ring for Your NeedsUsing the correct O-Rings in an engineering application is an important job that is understood by many UK O-Ring suppliers. When it comes to Specialist Sealing Products for that matter, only the experts can advise on what is the right way to use seals and O-Rings within the engineering application for which they have been designed.

O-Rings are so integral to engineering that they have even entered into the mainstream conversations of laypersons. In the 1980s, O-Rings were all anyone could talk about after the Chernobyl and Challenger disasters. It really brought home to the world how important they are.

With that in mind, here is a quick list of some points to consider before placing an order for them with your UK O-Ring supplier.

1. Performance vs. Durability

When using an O-Ring in an application, some factors need to be taken into consideration before heading to the O-Ring finder. If they are for a short-stroke application, then a small diameter O-Ring will be suitable. Thick cross-sectional O-Rings are best suited to long stroke applications.

Optimum O-Ring performance depends on small details for them to perform and last for the estimated lifetime. Engineering applications rely heavily on hydraulic and pneumatic seals on any dynamic rod or piston to have a decent lifespan. The durability must in no way affect the efficiency of the seal in the hardware.

2. Correct O-Ring Material

The O-Ring can degrade if the materials in the application are not compatible. The seal material can swell if the wrong compound causes fluid to build up and seep. The long-term usage of O-Rings relies on no chemicals being present during its functionality that could corrode it.

3. Temperature

Every temperature extreme that the O-Ring will be subjected to during performance must be taken into consideration. An O-Ring is produced with a certain amount of flexibility, and this can be lost and become fragile with extreme cold. Alternately, if the O-Ring selected for the application cannot withstand high temperatures, it will degrade when exposed to them.

4. Pressure

Knowing what kind of pressures the O-Ring will be subjected to during its operation is very important. It is necessary to calculate some numbers and statistics before the correct O-Ring application is found.

If the O-Ring seal is to remain static, then a standard Shore 70A material will be adequate. This will also have to factor in the other criteria in this list for the application; we are dealing in estimates here.

If the calculations reach a pressure estimate of over 1,500 pounds per square inch, then add a backup O-Ring as this will prevent any slippage or swelling/eroded material.

5. Perfect Size & Fit

The material chosen for the O-Ring must be suitable for the elements with which it will interact. If it is too soft for the application, it can extrude. If it is too hard, then it can swivel and loosen. This will lead to leaks and loss of performance and durability.

The selection of the perfect O-Ring for the many engineering projects currently underway in the UK is always made easier with the help of a Specialist Sealing Product expert.
