Zatkoff 6858249 NBR O-Ring (Pack of 2)

This is an NBR O-ring supplied by Zatkoff Seals & Packings under part number 6858249. Zatkoff is a Michigan based industrial distributor of O-rings, seals, gaskets and engineered sealing products, founded in 1959, and it packages and labels seals with lot traceability data such as batch number and cure date.

An O-ring is a circular elastomer seal that sits in a groove and compresses between two mating parts to block the passage of fluid or gas. O-rings are used in static joints such as covers, flanges and fittings, and in dynamic applications such as hydraulic and pneumatic cylinders, valves and pumps.

NBR, or nitrile butadiene rubber, also known as Buna-N, is a general purpose O-ring elastomer commonly used with petroleum based oils and hydraulic fluids. The label on this package lists a cure date of 2Q23, which buyers use to track elastomer shelf life.

No published size data was found for part number 6858249, so buyers should match it against their own parts records or the original seal.

Available from King Surplus inventory in Del Rio, Texas.
