May 30, 2019 · As a sealing option, the crucial difference between Buna and Viton is the temperature range of the material’s function. Viton is the choice over Buna for high-temperature applications. Viton seals hold indefinitely at temperatures up to 400°F and can last up to 48 hours at temperatures up to 600°F. Buna is effective to 250°F.

Choose from our selection of Buna-N rubber seals in a wide range of styles and sizes. Same and Next Day Delivery.

In this guide, readers will explore the different types of buna seals, their applications, and the manufacturing processes involved. Additionally, we will delve into best practices for selection and maintenance, ensuring that you can make informed decisions for your projects.

In the world of sealing solutions, the choice between Viton and Buna O-rings is crucial for ensuring optimal performance in various applications. This guide delves into the unique properties, advantages, and limitations of both materials, particularly in the context of the Chinese manufacturing landscape.

We offer the largest inventory of specialty and standard sealing solutions backed by best-in-class technology, service and support. Compare Buna-N (NBR) vs FKM (Viton®) o-ring properties, …

Buna seals are made of butadiene and acrylonitrile. They’re often referred to as nitrile or Buna-N elastomers and offer high tensile strength and resistance to fuel and oil. Buna is less expensive than fluoroelastomers, making it a cost-effective option without having to sacrifice durability.

Aug 28, 2020 · Viton® A (Bisphenol AF Cured Fluorocarbon Elastomer) has excellent mechanical, chemical, heat and steam resistance. It is particularly well-suited for hot fatty and oil-based products. Viton® is especially good for hard vacuum service because of its high molecular weight and low gas permeability.

Mar 5, 2020 · Buna-N, also known as Nitrile, is the sealing industry’s most economical and widely used elastomer. This synthetic rubber material is ideally used for o-rings, gaskets, seals and custom molded components for a variety of industries and applications.

Made of Buna-N rubber, these seals resist oil, grease, salts, water, steam, and most detergents. They have a hollow construction, so they’re more compressible than solid seals. For technical drawings and 3-D models, click on a part number. Wd.

Dec 8, 2020 · Let’s break down the difference between Buna and Viton elastomer materials and the role each plays in your pump’s performance. Buna O-Rings (NBR, Nitrile) Buna seals are standard in most pumps and work well for most cleaning and fluid pressurizing applications.

Jun 23, 2016 · Versatile and petro-resistant, Buna works well in sealing applications. Buna balls withstand some of the most demanding automotive applications, as well as those listed below.

Jun 23, 2020 · Viton® and Buna are two of the most commonly used elastomers for rubber seals and sealing devices. These materials are known to be universal o-rings that offer excellent resistant properties and reliability.

May 12, 2023 · Buna seals — often referred to as Nitrile, Buna-N, Perbunan, or NBR — are made from a copolymer of butadiene and acrylonitrile. As they are constructed from a cheaper substance, one of Buna’s advantages over Viton is its cost-effectiveness. Additionally, they are more flexible at low temperatures and have a better compression set resistance.

Oct 15, 2020 · Buna, otherwise known as Nitrile, Buna-N or NBR, is an incredibly versatile synthetic rubber. The unique properties of this material make Buna an ideal material for O-rings, vulcanized or spliced O-rings, gaskets, and other sealing applications for various industries.

Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to their resistance to petroleum-based fuels and lubricants and their relatively low price.

We offer the largest inventory of specialty and standard sealing solutions backed by best-in-class technology, service and support. Compare FKM (Viton®) vs Buna-N (NBR) o-ring properties, …

Feb 16, 2025 · Buna and Neoprene are different types of synthetic rubbers, each with its unique characteristics and uses. Let's explore their differences in detail. Dive deeper with me as we uncover the specific uses, strengths, and limitations of each rubber type. 1 What is Buna short for? 2 What is the difference between Buna-N and Buna S?

Jan 13, 2016 · Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more than 48 hours. Buna on the other hand is only effective up to 250°F.

Mar 14, 2023 · Buna seals — often referred to as Nitrile, Buna-N, Perbunan, or NBR — are made from a copolymer of butadiene and acrylonitrile. As they are constructed from a cheaper substance, one of Buna’s advantages over Viton is its cost-effectiveness.

Dec 29, 2017 · When comparing Buna rubber, (also known as Nitrile, Buna-N, Perbunan or NBR) and fluorocarbon (also known as Viton) both provide excellent compression set resistance and both are designed to resist most oils and lubricants, especially petroleum-based lubricants.
