While there are dozens of unique elastomers used for specific applications throughout the world, this GFS "elastomer cheat sheet" discusses the properties of the most common types of o-ring elastomers. If your equipment or product uses o-rings, it more-than-likely contains one of these nine elastomer types.

As we continue the GFS series on Surface Finish, this next tech bulletin will help you understand the advantages and disadvantages of the most commonly used method of measuring surface finish: Ra
It monitors production and is a very stable and
The shape and size of irregularities on a machined surface have a major impact on quality, performance (leakage), and longevity.
Whether you're working with o-rings, gaskets, or oil seals, each has a unique surface finish recommendation. Optimizing and staying within the recommended limits will help your equipment maintain longer uptime and better sealing performance.
Improving and controlling the ideal surface roughness will usually increase manufacturing costs, which often presents itself as a trade-off between the cost to manufacture the hardware and application performance.
Properly defining, measuring, and controlling surface finish is critical to the functional reliability and service life of a seal.
The shape and size of irregularities on a machined surface have a major impact on quality, performance (leakage), and longevity.
In order to control the manufacturing process or predict a component’s behaviour during use, it is necessary to quantify surface characteristics by using surface texture parameters.
Part 5 of our video series on Surface Finish will discuss Amplitude Parameters.
Amplitude Parameters are measures of the vertical characteristics of the surface deviations.
In this section, we will dive into:
The shape and size of irregularities on a machined surface have a major impact on quality, performance (leakage), and longevity.
The quantification and management of surface irregularities, through the measurement of surface roughness, is necessary to maintain high product performance.
Part 4 will discuss:
1. Cut-off Length / Filter
2. Surface Profiles
3. Profile Lengths
The shape and size of irregularities on a machined surface have a major impact on quality, performance (leakage), and longevity.
The quantification and management of surface irregularities, through the measurement of surface roughness, is necessary to maintain high product performance.
Part 3 of our video series on Surface Finish will examine important elements of why and how we measure surface finish. The full table of contents is below:
Part 3 will discuss:
1. Why we measure Surface Finish
2. Types of surface roughness
3. How we measure surface finish
4. Contact & Non-Contact measurement considerations
For nearly every application, the finish on a surface plays a critical role, bringing an enormous impact on performance and longevity.
Each manufacturing process used to acquire a specific surface finish produces a characteristic direction (lay) to the surface which affects wear patterns, performance, and longevity
Gallagher knows it's imperative to bring attention to the importance of surface finish and its relativity to the performance of your seals.
