Oil Resistance: Key Advantage and Applications of Buna-N O-Rings

Buna-N O-rings are widely recognized for their impressive oil resistance. At Arizona Sealing Devices, we provide Buna-N O-rings for use in environments that experience constant exposure to oil, fuel, and lubricants. These O-Rings exhibit a number of favorable characteristics relating to oil resistance, including:

Superior resistance to petroleum-based oils: Buna-N’s chemical structure is specially formulated for prolonged exposure to petroleum-based oils, holding up well in even the most demanding operating conditions.
Excellent resistance to hydraulic fluids: Buna-N O-rings are highly resistant to hydraulic fluids, reliably preventing fluid leaks in industrial machinery.
Good resistance to greases: Buna-N O-rings can tolerate ongoing exposure to various greases used to lubricate moving parts in industrial equipment.

Buna-N O-Rings from Arizona Sealing Devices are ideal for systems and equipment requiring high oil resistance, including:

Automotive: Buna-N O-rings are often used in brake systems, engines, transmissions, and fuel systems.
Oil and gas: These components are frequently used in pumps, valves, and pipelines.
Industrial machinery: Buna-N O-rings perform well in industrial equipment such as compressors and hydraulic systems.

While Buna-N O-rings deliver excellent oil resistance, they are limited to temperatures between -40 °F and 250 °F (-40 °C to 121 °C). Additionally, Buna-N O-rings might not be suitable for applications that involve aggressive chemicals or solvents.

Mechanical Strength: Durability and Flexibility for Demanding Applications

Buna-N O-rings uniquely balance strength and flexibility, performing well in moderate- to high-stress environments. At Arizona Sealing Devices, we supply Buna-N O-rings for applications that require high resistance to abrasions, cuts, and tears. These O-rings have several favorable traits relating to mechanical strength, including the following:

Abrasion resistance: Buna-N O-rings keep their shape, even when exposed to friction or abrasive surfaces.
Ability to withstand moderate pressures: Buna-N O-rings can handle moderate pressure levels, making them suitable for many industrial applications.

A number of applications benefit from the mechanical strength of our Buna-N O-rings, including the following:

Automotive: Exceptional durability means they can easily withstand mechanical stresses in transmissions, engines, and braking systems.
Industrial machinery: Pumps, valves, and other industrial equipment benefit from Buna-N’s dependability in industrial settings.
General manufacturing: Buna-N O-rings serve a broad range of industrial applications thanks to their impressive mechanical strength.

Like applications that require oil resistance, the above applications will see the best sealing results in temperatures ranging from -40 °F to 250 °F (-40 °C to 121 °C). Further, while Buna-N is highly versatile, it may not be suitable for applications that use aggressive chemicals.

Additional Value and Benefits of Buna-N O-Rings

While oil resistance and mechanical strength are key features of Buna-N O-rings, they aren’t the only ones. Here are a few other reasons companies across industries rely on our Buna-N O-rings:

Tensile strength: Buna-N’s tensile strength ranges from 200 to 3000 psi with an elongation of up to 400%.
Versatility: O-rings come in various sizes, thicknesses, and shapes for almost unlimited applications.
Resistance to aging: Buna-N’s aging resistance ensures long-lasting performance, even in challenging conditions.
Adhesion to metal: Buna-N adheres well to metal surfaces, preventing leaks in applications that require a firm seal against metal parts.
Affordability: Buna-N O-rings offer impressive performance and longevity at a low cost.
