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.

The need for easy-to-compress, low-closure-force seals is rapidly increasing in many commercial, electronic and communications applications. If you require efficient, reliable seals for light-weight enclosures with minimal bolts, fasteners or latches in combination with thin sheet metal or plastic flanges, consider low closure force (LCF) seals. LCF seals can drastically reduce the amount of closure force (compression) and the resulting stress generated on the sealed components. These hollow cross-sectional seals offer the seal designer and user a low-closure-force sealing solution for many applications. They can be supplied as either:
- Long Length Extrusions
- Spliced Rings/Gaskets
- Cut to Length Extrusions
To date, the most common method for reducing closure force has been to reduce the Shore hardness of the elastomeric seal material or change to a foam-type of material. - September 24, 2021

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.

Fastener Seals consist of an inner rubber component used in conjunction with an outer metal washer that supports the sealing function of a fastener such as a screw or bolt. The rubber and metal combination create an ideal fit to eliminate any clearance gaps between the housing components and protects against potential leaks in many static applications.
Fastener seals are intended to take the place of an o-ring in certain assemblies. By using a fastener seal, there is no need to have an o-ring groove machined into the component that the fastener will pass through.
GFS offers 3 different Fastener Seal Profiles for purchase below. Standard sizes and materials are kept in stock for same day shipment.

A metal seal is used when the application conditions are outside the specification limits of a polymer; extreme heat, extreme cold, extreme pressure, or a vacuum. With significant resilience coupled with the right material selection/coating for an application, a metal seal can be a very durable seal performing dependably year after year.
O-FLEX™ METAL SEAL O-RINGS
O-FLEX™ metal O-rings are designed to provide a sealing option for high-pressure/high-temperature applications that require minimal spring back. The O-FLEX™ metal O-ring is made from high strength metal tubing that is coiled, cut and welded to size. It is available in standard cross-section increments of 1/32”. The O-FLEX™ metal O-ring seating load can be adjusted to the application by varying the cross-section and tubing

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.
