o-ring sizes
- July 21, 2022
O-Rings are solid-rubber, doughnut-shaped seals used to block the passage of a gas or liquid when pressed between two mating surfaces.
They are amongst the most widely utilized seal designs in the world. Due to the number of ways they can be utilized, there are essentially an endless number of O-Ring sizes.
But despite the wide range of O-Ring sizes, every O-Ring has the same two dimensions: the inner diameter (ID), and the cross-section (CS). To attain an adequate seal, it must achieve proper compression, approximately 18-20% in the cross sectional characteristic. This creates a boundary to keep fluids in and contaminants out.

What does a typical repair and refurbishment of a single cartridge mechanical seal look like?
In this new mechanical seal video, GFS Mechanical Seal expert Lino Dimichino, discusses the typical mechanical seal repair and refurbishment process of a cartridge mechanical seal. This important service can help bring new life to your existing mechanical seals without having to purchase a new one.
Many customers of GFS choose to go the route of repair and refurbishment of mechanical seals as opposed to purchasing new ones. It can be more cost effective in many situations, and can make your old seals look just like new.
But what does a repair and refurbishment of a single cartridge mechanical seal look like?

Part 5 - Basics of O-Rings - Intro to Failure Modes
We are excited to present to you part 5 of our O-ring webinar series. For this portion, Benjamin Mell, GFS Application Engineer and Regional Sales Manager, introduces you to O-ring failure modes. Ben will give a general overview of how and why an O-ring might fail, and how you can determine which kind of failure mode the seal experienced.
Then, Ben will dive into the first two O-ring Failure modes.

Part 4 - Basics of O-Rings - O-Ring Profiles
We are excited to present to you part 4 of our O-ring webinar series. For this portion, Benjamin Mell, GFS Application Engineer and Regional Sales Manager, will delve deeper into specific O-ring profiles. While a traditional O-ring has a circular profile, additional O-ring profiles and sub categories have evolved over the years to solve specific application challenges. We are going to review each of these profiles and their benefits.
Part 4 will discuss:
1. Standard O-rings
2. Cord-Rings
3. Quad Rings® / X-Rings
4. Encapsulated O-rings
5. Hollow O-rings

Part 3 - Basics of O-Rings - Core Applications
A static seal is one that remains stationary. And in a truly static seal, the mating gland parts are not subject to relative movement. Most O-ring applications are static.
But what happens when there is relative motion? That's where dynamic seals enter. In this new video webinar, Ben Mell, Regional Sales Manager at Gallagher will discuss reciprocating seals, rotary seals, o-ring design, and common applications to consider throughout the design process.

Original content can be found on Parker’s Blog.Sealing decisions are often left until the end of product development. By the time an email is sent to Gallagher Fluid Seals, the gland may already be fixed. This may not pose a problem in many applications, but it can often leave the seal engineer with few options. Having input from the seal expert in the early stages will allow for greater flexibility in choosing a seal and better chances at optimal sealing.

Cartex® Cartridge Mechanical Seal
EagleBurgmann's Cartex mechanical seal is fully pre-assembled is designed with greater attention to functional details like tighter tolerances for more accurate seal operation, greater axial movement to handle pump shaft movement, seal parts with robust cross sections for optimal seal stability in operation, and castings that meet ASTM A 351/351M standards for proven quality. The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications. Cartridge seals are easy to fit, and they keep your running costs down.
The Cartex® cartridge seal line now includes single and double seal versions for all standard operating modes as well as special versions. For example: the Cartex range is now applicable for sterile applications or installation in positive displacement pumps.

Elastomers are a high molecular weight polymer that exhibits little plastic flow, and has a rapid recovery from an extending or compressing force. Elastomers are produced naturally as gum rubber on commercial rubber plantations or manufactured synthetically. Today, more than 32 synthetic rubbers are known.
In Part 2 of our webinar series, Benjamin Mell, Regional Sales Manager at Gallagher Fluid Seals will elaborate on the most common types of elastomers used in o-ring applications. He will discuss their performance characteristics, application details, and pros vs. cons.

O-rings are the most common sealing product in the world. An O-ring is a versatile solution that will effectively seal every time, assuming that basic design parameters are followed. It is also an inexpensive sealing solution compared to other products. An O-ring should always be considered for a seal application due to its low price and availability.
This blog and is the first in a multi-part video webinar series on the basics of o-rings.
