Enhancing Performance and Safety of Static Radial Seals
O-ring and back-up ring combinations have long been the standard for static applications requiring high-pressure sealing. However, real-world applications often expose limitations, including installation challenges and performance issues. Standard O-rings may twist during installation, while back-up rings can be incorrectly positioned or damaged. These issues are further compounded by exposure to pulsating pressures and contaminants,

Double Chamfer Radial Seals
More often than not, an O-ring makes for a great sealing element. They seal over a wide range of pressure, temperature and tolerance. Normally they require very little room, are readily available, and easily sourced. However, there are specific applications that may be better

O-ring/back-up ring combinations have long been considered the industry standard for static applications at high pressures. In field use, however, they may show weaknesses with respect to their installation and operation in the application. Standard O-rings are often prone to twisting, while back-up rings are oftentimes not installed in the proper position or damaged during installation. Furthermore, this sealing combination may exhibit deficits when exposed to pulsating pressures and dirt. Parker has developed the HS radial seal profile as a viable alternative to to conventionally used O-ring/back-up ring combinations for static sealing applications at high pressures.
The robust symmetrical seal geometry and use of particularly extrusion-resistant Parker polyurethane compounds not only simplifies installation but also enhances the sealing effect in pulsating pressure conditions. As a result, service life is significantly extended.

Once again, Gallagher Fluid Seals is pleased to bring its readers another video. This time out, we're dealing with radial seal misalignment issues.
In this clip, Gallagher Engineering Manager Craig Beil discusses shaft run out and shaft eccentricity, two common radial seal misalignment issues.
