When I rebuild hydraulic cylinders I try to replace the O rings with
quad rings. They are better than O rings because of the two lip seals
rather than one seal of the O ring. They work better for moving parts.
For just a static seal like on an end cap O rings work fine.
You may have to remachine the groove to accomodate the quad ring.

Any tips on where to find data on what groove dimensions should be? I
checked my 26ed Machinery Handbook already.
