Introduction to O-Rings

Without knowing it, we come across or benefit from o-rings every day. They are an important element of sealing in any environment where you want to keep fluid or even air from passing through a specific area. At APG our goal is to provide you with insight into o-rings, so when you purchase our products you are as knowledgeable and familiar with the product as possible. Over the next several weeks we will be releasing a series of blog articles to explain some of the more important and interesting aspects of o-rings. We hope you will gain helpful insight from this series.

The History of O-Rings

Like all things, the o-ring had to start somewhere! As a fluid sealing and conveyance product manufacturer and provider, we find the history quite interesting and you just might too. While APG has been providing the sealing and conveyance products that you need since 1943, the o-ring was invented in 1936. We will share interesting details about how the patent for the o-ring was purchased for $72,000 from a Danish-born inventor.

Overview of Rubber O-Ring Selection

O-rings are one of the most common products used for fluid sealing today. That being said, o-rings are not one size fits all. Our goal is to help you learn more about our o-ring selection so you can quickly and easily identify what products you need for every application. We will cover a variety of important specifications of an o-ring including but not limited to:

Understanding these specifications will help you confidently purchase the o-rings you need for every application!
