With four points of contact for a strong seal, these X-profile O-rings are often used in dynamic applications, such as on pistons and rotating shafts. Also known as Quattro seals and X-rings, they resist rolling and twisting better than round- and square-profile O-rings.

Seal moving parts up to 450° F. Also known as Quattro seals and X-rings, these are the top choice among our silicone O-rings for dynamic applications.

Made of Viton® fluoroelastomer, this cord stock resists a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol. It has four points of contact with surfaces, so it’s less likely to roll or twist in moving parts than round- or square-profile cord stock.
