Pump Buna-N O-Ring

Buna-N O-Rings are commonly used in General Pumps because they offer a high level of resistance to water, oil, fuel, and other chemicals. Whether it's needed for a seal, hose, or gasket application, you can expect a Buna-N O-ring to deliver superb performance and reliability. The specific material used in a Buna-N is called nitrile rubber or NBR. The black, highly-durable material resists weathering, can withstand a wide temperature range, and works smoothly with grease or hydraulic fluids. For these reasons, Buna-N is a popular, general purpose choice when dealing with pumps of all sizes. Specifically, the 90360400 from General Pump works wonderfully with their line of triplex plunger pumps such as the TC1506GUI.

Which is Better Buna-N or Viton?

When deciding between Buna-N and Viton for O-Rings, it is essential to consider the specific application requirements. Buna-N O-Rings, made from nitrile rubber, are renowned for their excellent resistance to oil, fuel, water, and various chemicals, making them a versatile choice for many industrial applications. However, Viton, a type of fluoroelastomer, offers superior resistance to high temperatures and harsh chemicals, which might be necessary for more demanding environments. Furthermore, Viton O-Rings are less prone to swelling in hydrocarbon applications, making them ideal for use in chemical processing or automotive industries. Despite this, Buna-N is often more cost-effective, hence frequently preferred for general-purpose sealing solutions where extreme conditions are not a factor. Therefore, selecting between Buna-N and Viton O-Rings hinges on a careful assessment of the operational conditions, including temperature range, chemical exposure, and budget constraints, to ensure optimal performance and cost-efficiency.
