Aerospace Rubber NBR O Ring Repair Kit -40°F - +257°F Operating Temperature

 

O-ring kits are an economical way to purchase seals for many businesses. With a variety of sizes in each kit, you can quickly find what you need to replace a damaged or missing O-ring without shutting down your line. Each kit includes popular O-ring sizes suited for a range of sealing applications.

Our 70-durometer nitrile (Buna-N) O-ring kits may be purchased with no label, a Parco label, or a generic label. Each kit includes 382 pieces, ranging in size from -006 to -327.

 

Nitrile / NBR: Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum products, operating temperature range (-40°F to +257°F) and one of the best performance-to-cost values. It's an ideal material for aerospace, automotive, propane and natural gas applications. Special Hydrogenated Nitrile (HNBR) compounds can improve resistance to direct ozone, sunlight, and weather exposure while increasing temperature range to +300°F
