Is NBR Rubber Resistant to Oil?

The most popular and reasonably priced elastomer in the seal industry is nitrile, commonly referred to as NBR rubber and Buna-N. This is partially due to its exceptional resistance to fuels, water, alcohols, silicone greases, hydraulic fluids, and oils derived from petroleum.

What Makes NBR Useful?

automobiles. In the automobile industry, NBR is frequently utilized in oil hoses, grommets, seals, and other components because of its robust resistance to lubricants and fuels. Aircraft. Similar to the automotive sector, NBR is perfect for gasoline and oil oses, grommets, fuel tanks, and seals because to its resilience to chemicals and fuel.

What Drawbacks Does NBR Have?

Why Is Teflon Used in Some Oil Seals?

PTFE Gaskets. Traditional radial shaft seals composed of elastomeric sealing lip materials cannot endure harsh environments, high temperatures, high pressures, or dry running. Radial shaft seals with one or more PTFE sealing lip(s) are made to withstand these conditions.

Which Is Superior, NBR Or Viton?

In terms of durability, Viton and Nitrile might be tied, depending on the use and environmental factors. In conclusion, Viton seals are more resistant to hard circumstances and external factors, while NBR seals are more durable in dynamic situations where flexibility is crucial.

How Does NBR Affect Oil?

This synthetic elastomer, also referred to as nitrile-butadiene rubber (NBR), is resistant to mineral and vegetable oils as well as extended and continuous contact to petroleum-based oils. For parts that are used in these kinds of materials, it is among the best oil-resistant rubbers on the market.

What Is A Substance for Sealing Oil?

Buna (Nitrile) and Viton® are the materials used in oil seals the most frequently. The most common elastomer used in sealing is buna (nitrile) oil seals. Hydraulic fluids, mineral oils and greases, alcohol, water, steam, and petroleum oils and fuels all pose significant threats to nitrile oil seals.

These seals are of excellent quality. There are no apparent signs of excess material or unfinished edges. I can hardly distinguish them from the set I already own, which is manufactured by all balls racing.


When it comes to O-rings, I never seem to need them until there's an urgent repair or assembly project underway. This typically triggers a frantic search to find the specific O-ring required. Unfortunately, local hardware stores usually stock O-rings solely for domestic plumbing fittings, packaged in blister packs that prevent trying them out, and often sold at steep prices. Fortunately, Gelisen offers a comprehensive kit of O-rings, presenting a wide variety of sizes. Ranging from small ones at just a couple of mm in inner diameter to larger ones approaching 24mm in inner diameter, the kit covers all bases. It's worth noting that the vendor labels the sizes of these O-rings based on their outer diameter. These O-rings are constructed using NBR nitrile rubber, the go-to material for most O-rings manufacturing. This ensures their durability and longevity. Although the vendor doesn't explicitly mention it, these O-rings are typically capable of withstanding high temperatures, reaching up to 250°F, and are even suitable for food contact. While I might be hesitant to use them for food applications, if I were to do so, I would first boil them to clean them thoroughly and test their temperature resistance.
