RTJ Flanges vs RF Flanges

Ring type joint and raised face flanges are two of the most popular options in the industry today. When we talk about these types of flanges and their differences, we are referring to choosing the best type of flange to create an effective seal. Today we’re going to...

Flange Faces

As you start to consider purchasing flanges or gaskets, you’ll see a variety of terms used that you may not have come across before. Flange faces are the surface area that will receive the gasket, allowing them to come together to create a seal when put under...

Octagonal Ring Type Joints

A ring-type joint is a metallic ring that is machined to sit between two mating surfaces, where it will be compressed to provide a high-quality and reliable seal. Ring-type joints are vital components in various applications across multiple industry sectors,...

Blind Flange vs Blank Flange

Small pieces of mechanical equipment flanges continually play a vital role across numerous industries and applications. In essence, we use flanges to connect pipes to each other, with flanges also found in valves and specific application fittings too. Due to the...

Types of Flanges

Businesses in a variety of industries rely on flanges to join pipes or components together or to keep equipment secured to a surface. When it comes to choosing the best types of flange for your processes, you’ll want to take the time to research the different options...

Threaded Flange

Threaded flanges are probably the most recognisable of all flanges due to their screw thread design that is used to connect it to the pipe. Threaded flanges, also known as screwed flanges (for obvious reasons), require a male and female thread to create a connection...

Slip On Flange

A slip-on flange can also be known as a hubbed flange, which, as the name suggests, has a hub with a very low profile. Why is this important? Because this type of ring type joint gasket has an internal diameter larger than the connecting pipe, allowing you to slide it...

Weld Neck Flange

Also known as tapered hub flanges or high hub flanges, weld neck flanges are a specific type of gasket with a protruding ridge and long neck used to connect pipework and provide you with a high-quality seal. Weld neck flanges, in particular, are a popular choice when...

Nitrile vs Viton® – What is the Difference?

As you start to make a decision about what type of O-rings to purchase for your business, you might wonder what material is the most suitable for your unique needs. Every business operation has different requirements for their O-rings, such as the temperature,...

Aflas vs Viton

When it comes to choosing O ring suppliers in the UK, you’ll find that there are a wide range of materials on offer for you to choose from. Many people find that the options can seem quite overwhelming, with some materials having similar properties but offering...

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.
