Nitrile Rubber O Ring Cord is one of the most commonly used materials for making custom sized O rings. This particular cord is extruded from 70 Durometer Nitrile Rubber Compound which is also often referred to as NBR (Nitrile Butadiene Rubber).

Nitrile Rubber is often used because of its combination of resistance to hydrocarbon fuels, mineral oils and greases as well as its excellent flexibility and sealing performance. This cord can be easily shaped and provides good, long lasting seal performance.

O Ring Cord is a simple, round, rubber extrusion. It is usually cut to length with both ends then joined with a super glue (or another adhesive) to make an O Ring. This is often done when custom sized O rings are urgently required or when the size of the ring makes arranging a fully moulded O Ring impractical.

O Rings made using our Nitrile Rubber O Ring Cord will exhibit the sealing capabilities of the nitrile rubber. Thus, you can expect them to withstand temperatures between -20°C and +90°C and offer excellent resistance to fuels, mineral oil based fluids, greases and water. Nitrile is typically not used for sealing aromatic hydrocarbons or brake fluid.
