What are Large O-Rings?

Large o-rings are often required when heavy machinery is in use, as the standard size may not be suitable for the equipment you are using at the time. They are made using various different processes, but you’ll need to find out which big o-rings are the right choice for your needs. This will come down to how you are planning to use them and the work you are doing, so make sure you are certain about the specifics of your job before getting started.

The first thing to consider when selecting big o rings is the size that you need. The definition of large o-rings is 35 inches or larger in diameter. Therefore, if you need something smaller, you’ll want to look at other solutions, such as encapsulated o-rings. A small size will require a different type of production method. Make sure you are also aware of the time it may take to receive the o-rings you need. When they have a more complicated design, you need to give a good amount of time to the company you are working with to create the o-ring solution for your project.

Of course, o-rings of any shape and size will cost different prices, and you’ll need to plan ahead for this expense. If you are buying o-rings for use with oil and gas or a vacuum, you will need a different production method for this type of project. For the most cost-effective solution, make sure you plan ahead and get in touch with our team to avoid delays to your project.

How is Big O Rings Produced? 

There are various production methods for large o-rings, but the one that’s used will depend on your project and budget. These are the three most common options which any o-ring supplier in the UK will be happy to offer to your business: 

  • Continuous moulding – This solution is best used for o-rings that will be used within oil and gas or vacuum applications. It will offer the same high quality that you experience will traditional techniques, and the joints in the finished product are almost undetectable. This means the o-rings are more consistent, but they need at least two to four weeks to create. Unfortunately, there’s also a high scrap rate within this type of production, meaning they are usually far more expensive. An extruded cord is moulded and cured into an arc, which will then be fed into the system. This creates a ring that doesn’t have a join and is uniform throughout. 
  • Precision vulcanisation – This is generally the best value for money solution and is ideal for more simple applications. It still offers a high-quality solution and lower leak potential. It uses a 45-degree angle scarf cut end with a fully cured extended cord. The lead time is just three to 14 days, but this solution won’t work for high-pressure or vacuum applications. Therefore, it’s not used as frequently in the industry, as it can’t be applied to every type of project. 
  • Standard vulcanisation – Finally, the third production method that’s commonly used is called standard vulcanisation. This is very similar to the technique listed above but often uses a 90-degree angle cut instead. The joint isn’t always of the highest quality, as it is quite often created by hand. We only recommend using this production method for very basic or short-term applications, which involve little pressure. Lead time is still the same as the above-mentioned method, so it is a good solution for last-minute projects.

Before working with a company to create large o-rings for your business, you’ll want to ensure you know the application they will be used for. This will help you to select the right option and production method for your needs and ensure you have o-rings that support your work. While it can be tempting to opt for the quickest solution, this isn’t always the best route to take. You may find that by rushing the process, you have more issues later down the line, which is something no one can afford when working with high pressure, gas, or oil.
