Sealing system keeps tunnel industry digging
Tunnels are getting larger, deeper, and excavated in more challenging conditions. There is also growing pressure to successfully complete these projects while meeting increasing demands for performance, on-schedule delivery, and safety. However, on many projects, concrete tunnel segments are fitted with rubber gaskets onsite and secured using adhesive, which can lead to time-consuming and cost-intensive…
Taking the simple O-ring to new levels
Edited by Mary C. Gannon, Senior Editor LSR (liquid silicone rubber) O-rings are growing in use in a variety of high-volume production applications, especially in life sciences. O-rings are the most commonly used seal, featured in applications from aircraft engines to chemical processing lines, the hydraulics in tractors to subsea down-hole tools. They account for…
Innovation for a new generation
Rotary seals may have been around since the 19th century, but 21st century needs demand changes in the design process as well as the finished product itself. There are rotary seals in almost every piece of equipment where parts revolve around an axis. From tiny rotary seals in dentist’s drills to giant ones on tunnel…

Hydraulic Cylinders Under Pressure
Today’s applications require that cylinders be pushed to move faster, use higher pressures, or last longer than ever before. In addition, they are expected to run with higher efficiency and minimal leakage. These conditions mandate that sealing systems work with optimum effectiveness. Matching the required sealing solution to cylinder demands is a straightforward process. First,…
