X-Rings, also known as quad ring seals, provide technologically advanced sealing capabilities that surpass that of standard O-rings. Quad rings provide enhanced leak protection through its innovative design that avoids spiral twists, while utilizing parting lines between the lobes instead of on the sealing surface. Since X-Rings provide less friction due to their innovative design, they require less maintenance and provide a longer seal life compared to standard O-Rings.
To get started on the quad ring seals or X-ring seals you need, use the filters below to find the I.D., O.D., and cross section (CS) dimensions you need. Then, follow the link to specify the material and hardness your project requires and request a custom quote.
