![]() Nitrile can be used in applications that come into contact with varying temperatures, including high temperatures. While Buna O-rings are more cost-effective than fluoroelastomers, they are vulnerable to high temperatures above 149° C. Its resistance to weather and ozone damage is significant but can be improved with the addition of other compounds. Buna-N is a nitrile-based synthetic product that has excellent abrasion and tear resistance and withstands exposure to some solvents. However, it is vulnerable to higher temperatures and chemicals such as brake fluid and halogenated hydrocarbons.īuna is for sturdy, general-purpose O-rings. The material has a strong operational temperature range from -50° C to 120° C, and hydrogenated nitrile can withstand temperatures up to 150° C. Nitrile can be compounded and processed into several different forms. Nitrile is a resilient elastomer used in a wide variety of industries, such as aerospace and heavy duty equipment. Nitrile O-Rings (Buna-N or Acrylonitrile Butadiene Rubber O-Rings) Pure silicone O-rings cannot withstand much in the way of wear, tearing, and other physical damage, so it’s best suited to static applications.Ĭommon industries that rely on silicone O-rings include: The material can handle a wide temperature range between -84–232° C, and resists damage from water, acids, ozone, UV radiation, and heat. Silicone O-rings are important components in outdoor and plumbing systems. PTFE O-rings are commonly found in applications such as automotive steering, chemical processing gaskets, chemical storage, and paint guns. Suitability for high-pressure applications.Resistance to cracks, stress, and chemicals. ![]()
