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...

AFLAS o ring

O rings come in many different dimensions, thicknesses, and materials. And it is the various different materials that o rings can be manufactured from that make each o ring unique and suitable for specific applications.

In fact, there are hundreds of different types of o rings to choose from and customise, which means, for you, there is an o ring available from your O-ring supplier that is perfect for your application.

One such material is AFLAS, which we will look at in more detail, including the benefits and makeup of the AFLAS material, and more in this post.

What is aflas o-ring

What is an o ring?

An o ring is a gasket chosen to fit between two mating parts that form a tight seal when compressed together. The aim is to prevent any leaks or gas from escaping.

AFLAS O-rings (also known as TFE/P rubber) are great for those applications that require temperature, chemical, and/or steam resistance, with these types of o-rings typically used in the oil and drilling industries.

They comprise propylene and tetrafluoroethylene with a 54% fluorine content. The copolymer that the o ring contains allows it the ability to withstand extreme temperatures, which in some cases can equate to 250 degrees Celsius.

Of course, you can request a customised AFLAS o ring where material composition might change depending on your specifications and requirements. It is always worth speaking with a professional in the o-ring field to determine which material and o-ring type will be most suitable.

What makes AFLAS material a good choice for an o ring?

This type of material provides a high level of resistance to almost every environmental factor that it can come across.

For example, AFLAS O-ring material is resistant to:

  • Steam
  • Ozone
  • Chemicals/acids/bases
  • Solvents
  • Amines
  • Ammonia
  • Gamma-ray radiation
  • Brake fluids
  • Skydrol fluids
  • Acetone
  • Vacuum
  • Petroleum compounds
  • And so much more.

Making these o rings suitable for:

  • Oil seals
  • Shaft seals
  • V-rings
  • Packings
  • Gaskets
  • Critical applications
  • Wire and cable (insulation jacketing of cables)
  • Food and pharmaceutical applications
  • Automotive industry
  • Chemical processing equipment
  • Utilities and HVAC

However, please be aware that AFLAS O-rings are not resistant to chlorinated hydrocarbons, ketones, organic refrigerants, or carbon tetrachloride.

Benefits of an AFLAS O-ring

Reliable and durable. These o rings due to their resistivity can provide you with longevity, so you have peace of mind that performance is maintained for extended periods.

It can replace Viton o rings in specific applications as it can be exposed to a range of automotive fluids and still provide the same high-level performance.

Resistant to various solvents and a wide range of chemicals, it is an excellent choice for various industry sectors or if you’re working with aggressive chemicals.

It has low-temperature properties, so as well as being able to withstand high temperatures, managing the material makeup of the O-ring also allows you to create an AFLAS O-ring that can be used in low-temperature applications.

This particular type of o ring is suitable in the food and pharmaceutical sector where aroma is a concern. This is due to the o-ring material’s low aromatising properties.

AFLAS o rings have excellent thermal properties, providing exceptional heat stability properties and resistance. This makes them a particularly good choice for steam applications.

They are also flame resistant, with the o ring burning if it is directly exposed to fire and stopping when it is removed.

AFLAS O-rings can also be used as a general-purpose seal with a fair compression set, offering excellent permeation resistance and acting as a good electrical insulator.

Choosing the right o ring for you

Every o ring is designed to provide the same function, i.e., to create a seal within an application that provides a barrier to prevent leaks.

However, where each o ring differs is in its material composition, and choosing the right o ring for you will require you to understand what each material offers and how this will benefit the application and your unique specifications.

Once you have chosen the most suitable material, you can then begin to look at dimensions and quantities, specifying the o-ring groove, taking into account the potential swell of the rubber, possible expansion properties, and the mating of the two parts.
