Buna-N Gasket Supplier

Buna-N Gasket Supplier

Arizona Sealing Devices, Inc. has decades of expertise manufacturing high-quality sealing devices for use in the military, aerospace, food and beverage, water treatment, and other industries.

Buna-N is a versatile, oil-resistant material made from nitrile that’s used for rubber gaskets and other seals that need superior abrasion resistance and tensile strength. Learn about our standard and custom gasket supply services, the benefits of Buna-N material, and compatible applications for it.

Standard and Custom Buna-N Gaskets

Arizona Sealing Devices offers a selection of standard die-cut gaskets in a variety of sizes, shapes, and designs. We also supply custom gaskets.

Our experts can assist with material selection to ensure your gaskets meet the requirements of your application.

Value-Added Services

In addition to supplying gaskets, we provide a number of helpful services, such as:

  • Kitting and assembly: Custom seal assemblies, subassemblies, or the assembly of gasket kits. Labeling or part marking services are also available.
  • Inventory management: Vendor-Managed Inventory (VMI) optimizes your on-hand inventory and reduces lead times. Our consignment options and stocking programs support lean manufacturing and just-in-time (JIT) production.
  • Labeling and packaging: Includes Mil-Spec labeling and packaging services (e.g., MIL-STD-130, AMS 2817) for individual or lot segregation of seals and gaskets. This ensures product compliance and traceability for aerospace or defense contracts.

Buna-N Advantages in Sealing Applications

Buna-N is a widely used material for gaskets and seals, and is valued in many applications for these characteristics:

  • Cost-effective performance. Buna-N is more affordable than other specialty elastomers, yet still delivers robust performance. It is an economical choice for OEM applications, maintenance kits, and bulk gasket needs, without compromising reliability or quality.
  • Leak-proof oil sealing. This material has excellent conformability and oil resistance for reliable sealing in gearboxes, engines, hydraulic systems, and compressors. Buna-N can help prevent leaks of lubricants, oils, and fuels, even under pressure. It also has inherent adhesion to metal surfaces, creating tight seals that don’t slip.
  • Longevity and durability. Nitrile gaskets have good anti-aging properties. They are suitable for dynamic conditions and repeated use, and have excellent tear resistance.
  • Versatility. Different formulations of Buna-N are available to meet regulatory and industry requirements. Because it conforms and adheres well to metal, it can be used to fill gaps and compensate for minor flange imperfections.

Common Applications and Industries

Buna-N gaskets are found in critical sealing applications across industries. If standard options do not meet your requirements, Arizona Sealing Devices can create a custom gasket for your application.

Aerospace

Buna-N is not damaged by hydraulic fluids and oil. It is also suitable for typical aircraft operating conditions including high heat and vibration. Applications include:

  • Carburetors and pumps
  • Engines
  • Fuel systems
  • Fuel tanks
  • Hydraulic lines

Food and Beverage Processing

Food and Beverage Processing

In food-grade applications, nitrile rubber must be formulated to comply with Food & Drug Administration (FDA) requirements. White nitrile provides a safe sealing solution with superior resistance to food fats, vegetable oils, and cleaning chemicals in varying temperature conditions. It is often used in dairy and beverage applications to create the following components used with milk, juices, or edible oils:

  • Gaskets
  • Pipe couplings
  • Pump seals
  • Valve seals

General Industrial and Manufacturing

Buna-N gaskets are a reliable sealing material for use in manufacturing equipment, industrial machinery, and MRO applications requiring durable, oil-resistant seals at moderate temperatures, such as:

  • Assembly line equipment
  • Compressors
  • Gear boxes
  • Industrial pumps

Oil and Gas Industry

Oil and Gas Industry

Nitrile offers exceptional resistance to gasoline, crude oil, natural gas liquids, and diesel. It is widely used in the following applications for seals in pumps, valves, and pipe flanges to prevent hazardous leaks:

  • Fuel storage tanks
  • Oilfield equipment
  • Pipelines
  • Refinery equipment

Waste and Wastewater Systems

Buna-N is used in pump gaskets, plumbing gaskets, and water treatment equipment where general-purpose elastomers are required. Nitrile also has excellent resistance to mild chemicals and wastewater.
