White 7 mm Rubber O Ring Cord , Precision Extruded Static Seal FKM O Ring Cord

FKM 75 White O Ring Cord Resistance to High Temperature Rubber Strip

O-ring cord has an o-profile but is supplied as an extruded cord and can therefore be cut to the length that you require. O-ring cord can be used as a static seal for when standard sizes are either unavailable or too costly, and can be bonded or vulcanised to the size required. O-ring cord can be supplied in all standard materials and supplied in lengths or coils. We offer O-ring cord with standard sections, ranging from 1mm – 20mm.

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.

One thing to be aware of when making O rings with Nitrile or any other material, the O Ring will only be as strong as its weakest point; which is often the adhesive join. We’re pleased to be able to offer a complete range of high quality, German-engineered super glues to use to make strong, high performance O Rings.
