X-Rings, also known as Quad-Ring Seals, can be used in a wide variety of static and dynamic
sealing applications. In reciprocating applications, the X-Ring four-lobed design prevents spiral
failure and in rotary applications, it prevents the seal from bunching and failing. We supply both
Quad-Ring branded seals manufactured by Minnesota Rubber and Plastics, Quadion LLC as well
as similar seals described in various ways like X-Rings and Q-Rings.
The four-lobed design provides two sealing surfaces in comparison to a standard O-ring. Thedouble-seal action requires less force to maintain an effective seal. This reduction in force means
less friction and improved seal life.
X-Ring parting lines are between the lobes, away from the sealing surface, thus eliminating theproblems of leakage often resulting from a parting line's irregular surface as found on an O-Ring.
The unique design of the X-Ring allows it to be used in narrower grooves and also in standard
width O-ring grooves.
Quad-Ring vs O-Rings - What makes them better?
The O-ring is a doughnut-shaped circular cross section seal that can be used nearly anywhere in the sealing industry. The Quad-Ring, a 100% retrofit option for any O-ring application, can and will outperform an O-ring in many technical areas.
The Quad-Ring has four definitive sealing advantages over an O-Ring:
Hidden parting lines, or flash lines. The flash lines (a line of excess material where the compression mold tool comes together) on an O-ring is always on the outer most diameter, which consequently is a sealing surface. On a Quad-Ring, that flash line is on the inside of the two outer lobes; therefore, it does not effect the sealing lips.
The Quad-Ring is more stable in dynamic applications. It is also more resistant to rolling as it has a wider footprint and takes up the corners of the hardware groove. Spiral failure is common in dynamic O-ring applications in which torsion occurs and the ring can extrude or over-yield.
The Quad-Ring has great lubrication retention. The grooves on the inside and outside diameter of the ring retain lubricant, thereby lowering friction and extending packing/seal life.
Less compression force to seal. The multi-lobed design provides more sealing surfaces than an O-ring, all while using the same hardware (Quad-Rings are intended to be used in standard O-ring grooves). With these multiple seal points on one ring, less squeeze is required to provide an effective seal. Less friction and wear will ultimately increase service life and reduce downtime.
To recap, the Quad-Ring is a 100 percent retrofit design option for any current O-ring application. It follows the same standard sizing as O-rings as well.
