Ozone is a powerful oxidizing agent, capable of degrading materials that are not properly selected. Using the wrong materials can lead to <strong>leaks, system failures, and safety hazards<\/strong>, while choosing the right materials ensures longevity and reliable performance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Good Materials for Ozone Systems<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Materials that resist ozone oxidation and degradation include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Teflon<\/strong> (PTFE, FEP, PFA)<\/li>\n\n\n\n<li><strong>316 Stainless Steel<\/strong><\/li>\n\n\n\n<li><strong>Viton<\/strong><\/li>\n\n\n\n<li><strong>Silicone<\/strong><\/li>\n\n\n\n<li><strong>CPVC<\/strong><\/li>\n\n\n\n<li><strong>Kynar<\/strong> (PVDF)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These materials can be used without concern for ozone concentration or type of application. They are suitable for <strong>dry ozone gas, wet ozone gas, or ozone dissolved in water<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Materials to Avoid with Ozone<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Some materials are highly susceptible to ozone damage and should <strong>never<\/strong> be used in ozone applications:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Buna-N (Nitrile)<\/strong><\/li>\n\n\n\n<li><strong>Nylon<\/strong><\/li>\n\n\n\n<li><strong>Mild Steel<\/strong><\/li>\n\n\n\n<li><strong>Cast Iron<\/strong><\/li>\n\n\n\n<li><strong>Acetal<\/strong><\/li>\n\n\n\n<li><strong>Natural Rubber<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Using these materials can lead to rapid deterioration, leaks, or catastrophic failures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Considerations for Material Selection<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Ozone Concentration<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">High ozone concentrations accelerate material degradation. Industrial ozone generators can produce <strong>5% ozone gas or higher<\/strong>, while water treatment systems may deliver <strong>2 ppm or more<\/strong> in solution. At high levels, only top-quality materials should be used.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Type of Ozone Exposure<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Materials react differently depending on exposure:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Dry ozone gas<\/strong><\/li>\n\n\n\n<li><strong>Wet ozone gas<\/strong> (off-gas)<\/li>\n\n\n\n<li><strong>Ozone dissolved in water<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Components must be selected based on the type of ozone exposure in your system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Wet vs. Dry Ozone<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Wet ozone<\/strong> often reacts faster with certain materials due to moisture facilitating oxidation.<\/li>\n\n\n\n<li><strong>Dry ozone<\/strong> can oxidize surfaces more slowly, but long-term exposure can still degrade weaker materials.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Testing and Verification<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">While charts provide general guidance, <strong>testing in your specific application is often the best method<\/strong> to confirm material compatibility. Observing how the material performs under expected ozone concentrations, temperatures, and exposure conditions ensures safety and reliability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Consider Normal Oxidation Resistance<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A simple rule of thumb: materials that withstand <strong>normal oxidation outdoors<\/strong> or <strong>chlorine exposure in water<\/strong> tend to perform better with ozone. Materials that degrade under these conditions will degrade faster with ozone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Visual Examples<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Oxidized pipe fittings are an easy way to see the difference between ozone-resistant and ozone-vulnerable materials. Components that oxidize quickly are usually lower-quality materials and should be avoided.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Resources for Further Information<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"http:\/\/chrome-extension:\/\/efaidnbmnnnibpcajpcglclefindmkaj\/https:\/\/www.oxidationtech.com\/downloads\/OzoneMaterials.pdf\" data-type=\"link\" data-id=\"chrome-extension:\/\/efaidnbmnnnibpcajpcglclefindmkaj\/https:\/\/www.oxidationtech.com\/downloads\/OzoneMaterials.pdf\">Durability test results<\/a><\/strong> of construction and process materials exposed to liquid and gas phase ozone<\/li>\n\n\n\n<li><strong><a href=\"http:\/\/chrome-extension:\/\/efaidnbmnnnibpcajpcglclefindmkaj\/https:\/\/www.oxidationtech.com\/downloads\/EcoSensors\/Ozone-Resistance-Chart.pdf\" data-type=\"link\" data-id=\"chrome-extension:\/\/efaidnbmnnnibpcajpcglclefindmkaj\/https:\/\/www.oxidationtech.com\/downloads\/EcoSensors\/Ozone-Resistance-Chart.pdf\">Ozone resistance chart<\/a><\/strong> from EcoSensors \u2013 Tech Tip<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/www.oxidationtech.com\/ozone_resistant_materials\" data-type=\"link\" data-id=\"https:\/\/www.oxidationtech.com\/ozone_resistant_materials\">Complete ozone-resistant materials chart<\/a><\/strong><\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing the <strong>right materials<\/strong> for ozone systems is crucial for <strong>safety, longevity, and efficiency<\/strong>.
