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

Tips on waterproofing components in harsh environments

By Andrew Weiman, Managing Partner Engineering and Commercialization, Bresslergroup Three key steps will ensure components are properly sealed against liquids. Engineering products for use in harsh environments is both an art and a science. Though conceptually simple, the challenges of sealing tend to surprise and frustrate those without experience and continually challenge even experienced designers.

Silicon Seals for any Application

Seals and O-rings come in a variety of materials, including elastomers that have passed USP Class VI testing, such as Viton® fluoroelastomer (FKM) and EPDM rubber. These elastomers also feature improved chemical resistors, excellent heat resistance (400° F/200° C), and low permeability to gases. They are available as microminiature O-rings, and products such as molded

Elastomer O-Rings are not your only option

Elastomer O-Rings are a common choice for sealing within semiconductor equipment. However, ions can leach, leading to contamination. They can also deteriorate quickly when subjected to aggressive media and gases. The Turcon® Variseal® is another sealing option. Turcon, a PTFE-based material, is compatible with virtually all chemical media and has superior wear resistance, and can
