Quad-Rings, also known as X-Rings
Quad Rings can be used in a wide variety of static and dynamic sealing applications. With the unique 4-lobe configuration, X-rings have 2 sealing areas per side as opposed to 1 sealing area on an O-ring. X-rings require less squeeze to maintain an effective seal; therefore, reducing friction and increasing seal life. Their 4-lobe configuration also helps to eliminate the seal from twisting in the groove causing premature failure.
Q-rings have the same dimensions as the AS568A O-ring sizes, also referred to as standard size O-rings.
