The compatibility data shown on this web site has been compiled to assist in evaluating the appropriate materials to use in handling various gases. Prepared for use with dry (anhydrous) gases at normal operating temperature of 70°F (21°C), information may vary if different operating conditions exist.
It is extremely important that all gas control equipment be compatible with the gas being passed through it. The use of a device that is not compatible with the service gas could damage the unit and cause a leak that could result in property damage or personal injury. To reduce potentially dangerous situations, always check for compatibility of materials before using any gases in your gas control equipment. Systems and equipment used in oxidizer gas service (i.e. oxygen or nitrous oxide) must be cleaned for oxidizer service. Since combinations of gases are virtually unlimited, mixtures (except for ethylene oxide/halocarbon and ethylene oxide/carbon dioxide sterilizing gas mixtures) are not listed in the Compatibility Chart. Before using a gas mixture or any gas not listed in the chart, please contact your Scott Representative for more information.
