Despite endless time and effort, sometimes it’s tough to achieve perfection — and O-Ring design flaws happen periodically. By having thorough knowledge of overcompression issues, engineers can achieve the proper leak path ratio and avoid premature failure in O-Ring applications.
Low temperatures raise big concerns for rubber manufacturers. Applications in major industries like automotive, railroad and industrial processing demand peak seal performance in cold, harsh environments. See how we evaluate cold temperature properties through several different test standards.
O-Rings make or break fluid-power systems. These small-but-mighty components are crucial to the success of an application. In our latest short video, we cover some of the most common causes of O-Ring installation issues so you can prevent O-Ring problems as early as the design stage.
When the pressure on an o-ring is increased to the point that it can no longer resist being extruded into the diametrical gap, and to compensate for loose fitting components, the use of backup rings to block the diametrical clearance gap and provide support for the o-ring may be a viable solution. A backup ring is made of a harder material than the o-ring itself, but sufficiently resilient to deform under pressure to close the extrusion gap.
Tell me if this sounds familiar: You’re ready to go into testing with your design and the last step is the sealing requirement. You review the design guidelines, rules of thumb, and use the interactive calculators to find the perfect o-ring. Then, you check for its availability and it’s not in stock. Now what?
