Sterling Seal ORTESI228X250 228 Teflon Encapsulated O-Ring, Silicone FEP/TFE (Pack of 250)

Sterling Seal & Supply Teflon Encapsulated Silicone "O" Rings with FEP or PFA are designed to address the growing problem of sealing in the most hostile chemical and temperature environments Teflon Encapsulated Silicone "O" Rings combine the best qualities of two materials, FEP or PFA on the outside with its chemical inertness and an elastomer on the inside for resilience This unique combination forms a highly effective, long lasting seal for the most demanding applications Sterling Seal & Supply Encapsulated O-rings are O-rings consisting of a seamless and uniform Teflon FEP/PFA encapsulation/jacket which completely encloses a core material of silicone elastomers The combination of these components creates an O-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments Sterling Seal & Supply Encapsulated O-rings have a high chemical resistance Chemical attack and swelling are the primary causes of O-Ring failure Encapsulated O-rings from Sterling Seal & Supply are virtually chemically inert Our American-Made Encapsulated O-rings match the chemical and temperature resistance of solid PTFE O-Rings; encapsulated O-rings possess properties of elasticity and recovery which are crucial in many sealing applications Encapsulated O-rings from Sterling Seal & Supply economically and effectively replace Kalrez and other exotic O-Ring compounds Our encapsulated O-rings will decrease downtime and hence increase profitability wherever corrosive fluids and gases cause premature seal failure Sterling Seal & Supply encapsulated O-rings withstand breakdown caused by industrial solvents and corrosive materials at elevated temperatures from -60° C/-75° F to +205° C/400° F
