Buna Standard Size O-Rings

Request A Quote

Buna (or Nitrile) material is great for all but the most extreme applications. It works from -40-degrees F to 250-degrees F, and has good wear resistance. It works with oils but does not work with brake fluid, ketones, and some hydraulic fluids. It is not resistant to weathering, sunlight, and ozone unless a special compound is used. Standard or Imperial sizes come in fractions of an inch.
