Zatkoff Offers Complete Inventory of Parker N674-70 O-Rings

July 10, 2018

 

Even when used in equal applications, it's common to see the same type of NBR-70 O-ring perform differently. These variances are due, in part, to the instability of physical and chemical properties caused by inconsistent compounding and processing.

We solve this performance issue with Parker's N674-70 O-rings. Zatkoff Seals & Packings is committed to consistently providing reliable, solutions-based products and services that meet its customers diverse needs.

In line with this commitment, we are proud to carry the largest N674-70 inventory in the world. Offering more than 4 million parts in stock, we can ensure access to N674-70 regardless of size, coating, or marking requirements.

Known for its excellent mechanical properties, including tremendous heat resistance, N674-70 nitrile rubber O-rings are compatible with a variety of oil and gas applications. Parker's N674-70 have a recommended temperature range of -30°F to 250°F and can be effectively used with aliphatic hydrocarbons, vegetable and mineral oils, and greases.

In addition to the extraordinary stock offerings at Zatkoff, we also provide all available variations of the N674-70 AS568 standard sizes. Adherence to this widely-used standard ensures full material availability of N674-70 O-rings to our aerospace, automotive, oil and gas, and general purpose manufacturing customers when oil and heat resistance is a requirement.
