X-ring Seals Run Circles Around O-rings! What Makes X-Ring Seals Better?. Twice the Sealing Surface — Multi-lobed design provides more sealing surfaces than standard O-Rings. . Prolonged Seal Life – With multiple seal points, less squeeze is required to provide an effective seal. Less friction and wear will increase seal life and lower maintenance costs. . Prevents Spiral Failure – The “X ” profile creates a stable seal that is more resistant to rolling in the groove than an O-Ring when used... (read more)
Rings Rings. MWI divisions utilize both coiling and stamping processes to manufacture rings with diameters up to 40 inches. Coiled rings can be produced from round or shaped wire. Our in-house wire shape rolling and ring grinding capabilities enable us to provide close tolerance rings while minimizing raw material lead-time. Our proprietary shot peening process for light rings has improved the fatigue life of or rings many times over, enabling some of our customers to improve product life without... (read more)

Quad-Rings / Square Rings X-Rings, also known as Quad-Rings®, can be used in a wide variety of static and dynamic sealing applications. The four-lobed design provides twice the sealing surface in comparison to a standard o-ring. The double-seal action requires less squeeze to maintain an effective seal. This reduction in squeeze means less friction and improved seal life. X-Ring parting lines are between the lobes, away from the sealing surface, thus eliminating the problems of leakage often resulting from a parting... (read more)

Quad-Rings a Quad-Ring® seal uses a narrower groove than a comparable O-Ring seal. Longer Seal Life. Because less squeeze means less friction with the four-lobe design, seals last longer. This means equipment in which the Quad-Ring® seal is installed will operate longer and require less maintenance. No Parting Line on Sealing Surface. Unlike O-Rings, where partitioning lines are on the sealing surface, Quad-Rings® seal's parting lines lie between the lobes, away from the sealing surface. This design...
