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...

How choosing the correct gasket reduces risks

Health and Safety across any industry are vital, especially so in industrial facilities and settings.  Why?  Because harmful leaks and emissions must be avoided at all costs to avoid serious accidents or injury to your teams and property.  That’s why having the right...

How to tighten your bolts perfectly

How to tighten your bolts and which tools you should use to achieve the perfect seal is not as seamless and straightforward as we would like. Various factors come into play in these situations, such as bolt grade, size, and even application type.  Tightening torques...

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.
