Metal Seal Profiles
At Gallagher, we often receive unique requests for challenging projects, and customers who might be intimately familiar with elastomeric seals might have a better fit utilizing metal seals for their application. But, why might someone use a metal seal?
What is a metal seal and how are they used?
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 may be too excessive for typical rubbers or elastomers and demand a metal seal. 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.
In order to understand metal seals a bit better, GFS thought it might be worthwhile to discuss metal seal terminology, and different profiles.
This is a short guide to reference common terms and profiles that may to new to end-users.
In this blog post, we will discuss the following:
- Common terms of metal seals
- Standard formed metal seals
- O-rings
- C-Rings
- Spring energized C-Rings
- U-Rings
- E-Rings
- Metal Wire Rings
- Axial C-Seal
- Boss Seal
