Our Products


American Rubber Corp is a leading manufacturer of variety of sealing solutions. Quad ring manufacturing is one of our many specialty. We design, manufacture, and supply X rings to our customers for their mission critical dynamic sealing application where pistons, rods, spindles have rotory or reciprocating movements (sometimes both). We produce high quality, long service life quad rings from best materials that is suitable for your specific application needs.

A Quad Ring or X-Ring, while looks similar to O ring, with the cross section shape that conforms to X profile or 4 dove tail profile creates 4 contact surfaces. These shapes provide multiple contact points for sealing which provides redundant and secure sealing (twice as compared to normal O rings) suitable for most critical applications. Another improvement that Quad rings provides over O ring is reduced break out friction. Quad ring with its 4 contact surfaces mitigates risk of spiraling displacement of seal which is common with regular O rings if used in dynamic sealing applications (where rotary and reciprocal movements of parts needing sealing is involved).

Typical use of X Ring or Quad rings include:

  • Hydraulic rods or plungers where reciprocal movements are common
  • Rotating spindles or shaft where rotary movements are common
  • Along with Bushings where radial or axial static seal is required

We also manufacture PTFE coated Quad Rings for our customers to provide excellent abrasive resistance. Please reach out to us at +1(317)548-8455 or submit our Request for Quote form.
