Enviroflex 500

Flexitallic Enviroflex 500 is a low-emission valve stem sealing system. Supplied as a five ring set, consisting of three molded graphite rings and two braided header rings specially formulated from high-performance carbon yarn. Enviroflex 500 has been developed for use in Linear and Rotary valves and has exceeded the most stringent requirements for fugitive emissions, resulting in less product loss and reduced emission penalties. Where PTFE is of concern as a potential source of corrosion, select Enviroflex 506. Typical Applications: high integrity valve stem sealing to reduce fugitive emissions in the petrochemical and chemical industry.
Typical uses: valve stem seals
