LATTYgraf 6940 EF

Industrial Valves : Packings for fugitive emissions applications

Packing made of expanded graphite yarns reinforced with Inconel wires, coated with a graphite-based mix doped with a friction-enhancing agent. LATTYgraf 6940 EF contains a corrosion inhibitor to protect the valve stem and the stuffing box. Heat transfer fluids and all high-temperature fluids. Note: LATTYgraf 6940 EF is recommended as anti-extrusion rings when used in combination with LATTYgraf 6960 EF, LATTYgraf EF4 ou LATTYflon 3260 LM. Limitation: precautions in oxydising environment Available in preformed packing rings, on request. Low-friction anti-extrusion packing for high-performance and high-temperature applications.
