Suitcase Style O-Ring Kits –

All CTP 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. CTPSN75 contains Nitrile 75 Hardness, substantially improving the lifetime of the component. CTP 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.
