Quad Rings

[sreid]

What are the primary uses of Quad Rings [X-Rings?] vs. O-Rings?

 

[EdDanzer]

We use them in higher pressure hydraulic components as they do not change shape as much and can be easier to install. Many spool valves use them instead of o-ring to seal the end of the spool.

We will be testing them as expanders under acetal seal ring for cartridge valve operating from 0 to 15,000 psi.

They are also used quite a bit in dynamic applications such as pistons.

Because of their shape they won't fail by being twisted, and also provide two points of sealing vs one provided by standard o-rings.
