The assortment contains 205 O-rings in a variety of SAE sizes. The hydrogenated nitrile constructed rings resists various temperature changes and resists more chemicals than standard O-rings. Includes a handy storage case with a sizing guide for easy organization and identification. A great O-ring set for most automotive and refrigerant applications.

• Hydrogenated nitrile-butadiene rubber withstands wider temperature variations and resists more chemicals than standard O-rings
• High tensile strength
• SAE sizes
• Idea for most automotive and refrigerant applications
