Square-Profile Oil-Resistant Buna-N Cord Stock
Made of Buna-N, this cord stock resists grease, hydraulic oil, and motor oil, plus mild chemicals and water. It’s also difficult to tear. It has flat edges on all four sides, so it covers more surface area than round-profile cord stock. This creates a tighter seal between flat, stationary surfaces. This cord stock is often used to seal flanged pipe connections, access covers, and electrical fixtures.
Make-your-own O-ring kits (sold separately) include everything you need to cut and bond this cord stock.

Square-Profile Chemical-Resistant Viton® Fluoroelastomer Cord Stock
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. Made of Viton® fluoroelastomer, this cord stock resists a wide range of chemicals, including benzene, boric acid, and ethylene glycol.

Square-Profile High-Temperature Silicone Cord Stock

Made of silicone, this cord stock remains flexible in temperatures as low as -60° F and as high as 400° F. It has flat edges on all four sides, so it covers more surface area than round-profile cord stock. This creates a tighter seal between flat, stationary surfaces. It’s FDA compliant for direct contact with food, so it’s often used to seal freezer doors or food processing equipment.

Square-Profile Water- and Steam-Resistant EPDM Cord Stock
Made of EPDM, this cord stock has excellent resistance to water, steam, and glycol-based fluids, including brake fluid. It has flat edges on all four sides, so it covers more surface area than round-profile cord stock. This creates a tighter seal between flat, stationary surfaces. This cord stock is also weather resistant, so it’s often used in water treatment tanks and other outdoor equipment.
Make-your-own O-ring kits (sold separately) include everything you need to cut and bond this cord stock.

Make-Your-Own O-Ring Kits with Cord Stock

Everything you need to make custom O-rings on demand. These kits include cord stock, a razor blade, a splicing jig, and adhesive. The adhesive does not work well on silicone—if you want to make silicone O-rings, consider a hot-bonding kit instead.
Buna-N resists grease, hydraulic oil, and motor oil, in addition to mild chemicals and water.
Viton® fluoroelastomer holds up to a wide range of chemicals. It also resists transmission fluid.
EPDM withstands water, steam, and glycol-based fluids, including brake fluid.
