Recommeded for petroleum products, air with oil vapors, vegetable and mineral oils with in the specified temperature range. Not recommeded for hot water services over +150°F (+66°C) or for hot dry air over + 140°F (+60°C).

# FIT products silicone gaskets are recommended for fire protection dry systems, all systems operating below 0°F (-18°C), plus dry heat, air without hydrocarbons, certain chemical services, and water to +160°F (+70°C).

NOTE:
Services listed are General Service Recommendations only. It should be noted that there are services for which these gaskets are NOT recommended. Reference should always be made to the latest Victaulic Gasket Selection Guide for specific recommendations.
Gasket recommendations apply only to Victaulic gaskets. Recommendations for a particular service do not necessarily imply compatibility of the coupling housing, related fittings or other components for the same service.

To assure the maximum life for the service intended, proper gasket selection and specification in ordering is essential.

Many factors must be considered in determining the optimum gasket for a specific service. The foremost consideration is temperature, along with concentration of product, duration of service and continuity of service. Temperatures beyond the recommended limits have a degrading effect on the gasket . Therefore, there is a direct relationship between temperature, continuity of service and gasket life.
