Improving Installation - Axial
Axial seals, also called Face Seals, are a very robust and common design for an O-ring or other type of seal.
Improving Installation - Radial
Radial seals, also called piston seals, are a very robust and common design for an O-ring or other type of seal.
Low Closure Force
The force needed to compress an O-ring can be significant. Especially a large or thick O-ring. This is generally not an issue for strong hardware materials, however it can be problematic.
Overcoming Gland Limitations
A variety of seal options are designed to offset hardware limitations.
High Pressures
The failure mode most frequently associated with high fluid pressure is extrusion. Material properties which greatly contribute to resisting extrusion are hardness and modulus of elasticity.
Dynamic Sealing
Dynamic sealing is considerably more involved than static sealing. Not only does a seal have to prevent the flow of some medium, like in static sealing, but it also has to be able to perform that task.

O-Ring Basics
For those who are unfamiliar with O-ring design, it is recommended to study this introductory section and become familiar with the basic principles of O-ring sealing, their common uses and general limitations. Even those who have designed many O-rings may profit by reviewing the basics from time to time.
Mobile InPhorm
O-Ring Design Analysis
Take the guesswork out of O-ring design and selection with Mobile inPHorm. This web based mobile app offers material recommendations, fluid compatibility, and gland/seal calculations (standard sizing design analysis). Recommended for basic design analysis.
O-Ring Selector
O-Ring Calculator
O-Ring Selector is a sophisticated sizing calculator with added features for estimating thermal expansion, chemical volume swell and compressive load force (uses imperial and standard sizing design analysis). Recommended for advanced users.
