Made of Buna-N, this cord stock resists grease, hydraulic oil, and motor oil. It also withstands mild chemicals and water.

Harder than standard Buna-N cord stock for better wear resistance.

The X shape of this cord stock provides four points of contact for a better seal in dynamic applications than round profile. It also requires less compression to make a seal, so it offers a longer service life.

The flat edges of this cord stock contact more surface area than round-profile cord stock, forming a tighter seal in faucets and other stationary parts. It’s also less likely to twist or shift in equipment with repeated pressure changes, such as molding machines.

With a 90A durometer, this cord stock is harder and more wear resistant than standard Viton® fluoroelastomer cord stock. It holds up in high-pressure equipment, such as fuel injectors.

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.

Our most chemical-resistant cord stock. Made of Viton® ETP fluoroelastomer, this cord stock resists steam and harsh chemicals, including hydrochloric acid, sodium hydroxide, and other strong acids and bases.

Made of silicone, this cord stock stays flexible across a wide range of temperatures. It’s often used to seal autoclaves, industrial dryers, and freezers.

Easier to compress than standard silicone cord stock, this cord stock creates a better seal on uneven surfaces. It withstands temperatures as low as -60° F and as high as 400° F.

Often used in marine environments, this neoprene cord stock resists moisture, salt water, and UV rays.
