O-Ring Kits
Suitcase Style O-Ring Kits -
All O-Ring Kits come in special protective suitcases, containing the most popular ring sizes.
Viton O-Rings have higher temperature resistance than regular O-Rings. SN75 contains Nitrile 75 Hardness, substantially improving the lifetime of the component. O-Rings can be use in any industrial application from automotive to heavy equipment. For more information about the differences between O-Rings, please look at the reference chart on the back of the page.
