RS PRO Nitrile Rubber O-Ring Cord, 1.78 mm Diam., 8.5 m Long


If you need to create a secure machine seal, this nitrile rubber O-Ring cord lets you produce circular gaskets with ease. It has a diameter of 1.78 mm and comes in a length of 8.5 m, so it's a simple and economical way to make multiple O-Rings of varying sizes.

This O-Ring cord is made from nitrile rubber, so it's a durable option that's suitable for use in a wide range of environmental conditions. You can use it at temperatures as low as -30°C or as high as +120°C, and even at intermittent temperatures of up to +150°C. By creating a vacuum between surfaces, the cord prevents air or fluids from leaking out.

This versatile product is useful for creating seals on devices ranging from engines and boilers to beer taps.
